Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013778, here are decompositions:

  • 5 + 1013773 = 1013778
  • 11 + 1013767 = 1013778
  • 37 + 1013741 = 1013778
  • 61 + 1013717 = 1013778
  • 67 + 1013711 = 1013778
  • 79 + 1013699 = 1013778
  • 97 + 1013681 = 1013778
  • 107 + 1013671 = 1013778

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 3778 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3778-10-01 (MMDYYYY (US, single-digit day))
  • 3778-01-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,013,778 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1013778 first appears in π at position 990,701 of the decimal expansion (the 990,701ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
