Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615564, here are decompositions:

  • 37 + 8615527 = 8615564
  • 73 + 8615491 = 8615564
  • 103 + 8615461 = 8615564
  • 241 + 8615323 = 8615564
  • 277 + 8615287 = 8615564
  • 367 + 8615197 = 8615564
  • 547 + 8615017 = 8615564
  • 577 + 8614987 = 8615564

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 8,615,564 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 8615564 first appears in π at position 941,730 of the decimal expansion (the 941,730ordinal-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.
