Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565644, here are decompositions:

  • 7 + 565637 = 565644
  • 31 + 565613 = 565644
  • 41 + 565603 = 565644
  • 47 + 565597 = 565644
  • 61 + 565583 = 565644
  • 73 + 565571 = 565644
  • 127 + 565517 = 565644
  • 137 + 565507 = 565644

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 565,644 and was likely granted around 1895.

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

Position in π

The digit sequence 565644 first appears in π at position 403,020 of the decimal expansion (the 403,020ordinal-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.
