Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717986, here are decompositions:

  • 5 + 8717981 = 8717986
  • 23 + 8717963 = 8717986
  • 47 + 8717939 = 8717986
  • 59 + 8717927 = 8717986
  • 113 + 8717873 = 8717986
  • 239 + 8717747 = 8717986
  • 269 + 8717717 = 8717986
  • 353 + 8717633 = 8717986

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 8,717,986 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 8717986 first appears in π at position 588,216 of the decimal expansion (the 588,216ordinal-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.
