Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719864, here are decompositions:

  • 17 + 8719847 = 8719864
  • 47 + 8719817 = 8719864
  • 443 + 8719421 = 8719864
  • 557 + 8719307 = 8719864
  • 563 + 8719301 = 8719864
  • 641 + 8719223 = 8719864
  • 653 + 8719211 = 8719864
  • 677 + 8719187 = 8719864

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 8,719,864 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 8719864 first appears in π at position 156,801 of the decimal expansion (the 156,801ordinal-suffix:st 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.
