Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709786, here are decompositions:

  • 5 + 8709781 = 8709786
  • 67 + 8709719 = 8709786
  • 73 + 8709713 = 8709786
  • 89 + 8709697 = 8709786
  • 109 + 8709677 = 8709786
  • 139 + 8709647 = 8709786
  • 199 + 8709587 = 8709786
  • 223 + 8709563 = 8709786

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 8,709,786 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 8709786 first appears in π at position 787,720 of the decimal expansion (the 787,720ordinal-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.
