Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719664, here are decompositions:

  • 3 + 8719661 = 8719664
  • 61 + 8719603 = 8719664
  • 73 + 8719591 = 8719664
  • 97 + 8719567 = 8719664
  • 181 + 8719483 = 8719664
  • 223 + 8719441 = 8719664
  • 337 + 8719327 = 8719664
  • 487 + 8719177 = 8719664

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 8,719,664 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 8719664 first appears in π at position 372,205 of the decimal expansion (the 372,205ordinal-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.
