Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619518, here are decompositions:

  • 7 + 8619511 = 8619518
  • 79 + 8619439 = 8619518
  • 97 + 8619421 = 8619518
  • 277 + 8619241 = 8619518
  • 307 + 8619211 = 8619518
  • 367 + 8619151 = 8619518
  • 421 + 8619097 = 8619518
  • 487 + 8619031 = 8619518

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 8,619,518 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8619518 first appears in π at position 762,946 of the decimal expansion (the 762,946ordinal-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.
