Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615386, here are decompositions:

  • 53 + 8615333 = 8615386
  • 107 + 8615279 = 8615386
  • 113 + 8615273 = 8615386
  • 149 + 8615237 = 8615386
  • 167 + 8615219 = 8615386
  • 419 + 8614967 = 8615386
  • 503 + 8614883 = 8615386
  • 557 + 8614829 = 8615386

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 8,615,386 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 8615386 first appears in π at position 922,820 of the decimal expansion (the 922,820ordinal-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.
