Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716780, here are decompositions:

  • 11 + 8716769 = 8716780
  • 53 + 8716727 = 8716780
  • 71 + 8716709 = 8716780
  • 89 + 8716691 = 8716780
  • 101 + 8716679 = 8716780
  • 167 + 8716613 = 8716780
  • 197 + 8716583 = 8716780
  • 227 + 8716553 = 8716780

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 8,716,780 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 8716780 first appears in π at position 770,598 of the decimal expansion (the 770,598ordinal-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.
