Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640604, here are decompositions:

  • 3 + 8640601 = 8640604
  • 17 + 8640587 = 8640604
  • 101 + 8640503 = 8640604
  • 197 + 8640407 = 8640604
  • 317 + 8640287 = 8640604
  • 353 + 8640251 = 8640604
  • 383 + 8640221 = 8640604
  • 443 + 8640161 = 8640604

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 8,640,604 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 8640604 first appears in π at position 498,675 of the decimal expansion (the 498,675ordinal-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.
