Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006978, here are decompositions:

  • 29 + 1006949 = 1006978
  • 41 + 1006937 = 1006978
  • 101 + 1006877 = 1006978
  • 131 + 1006847 = 1006978
  • 179 + 1006799 = 1006978
  • 197 + 1006781 = 1006978
  • 227 + 1006751 = 1006978
  • 239 + 1006739 = 1006978

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 1,006,978 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 1006978 first appears in π at position 644,470 of the decimal expansion (the 644,470ordinal-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.
