Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 107780, here are decompositions:

  • 3 + 107777 = 107780
  • 7 + 107773 = 107780
  • 19 + 107761 = 107780
  • 61 + 107719 = 107780
  • 67 + 107713 = 107780
  • 109 + 107671 = 107780
  • 139 + 107641 = 107780
  • 181 + 107599 = 107780

Showing the first eight; more decompositions exist.

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 107,780 and was likely granted around 1870.

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

Position in π

The digit sequence 107780 first appears in π at position 155,960 of the decimal expansion (the 155,960ordinal-suffix:th 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.
