Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631804, here are decompositions:

  • 17 + 8631787 = 8631804
  • 23 + 8631781 = 8631804
  • 61 + 8631743 = 8631804
  • 67 + 8631737 = 8631804
  • 131 + 8631673 = 8631804
  • 193 + 8631611 = 8631804
  • 271 + 8631533 = 8631804
  • 353 + 8631451 = 8631804

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 8,631,804 and was likely granted around 2014.

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

Position in π

The digit sequence 8631804 first appears in π at position 394,004 of the decimal expansion (the 394,004ordinal-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.
