Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723386, here are decompositions:

  • 83 + 8723303 = 8723386
  • 173 + 8723213 = 8723386
  • 263 + 8723123 = 8723386
  • 509 + 8722877 = 8723386
  • 557 + 8722829 = 8723386
  • 587 + 8722799 = 8723386
  • 647 + 8722739 = 8723386
  • 743 + 8722643 = 8723386

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 8,723,386 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 8723386 first appears in π at position 520,719 of the decimal expansion (the 520,719ordinal-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.
