Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565720, here are decompositions:

  • 53 + 565667 = 565720
  • 59 + 565661 = 565720
  • 83 + 565637 = 565720
  • 107 + 565613 = 565720
  • 131 + 565589 = 565720
  • 137 + 565583 = 565720
  • 149 + 565571 = 565720
  • 167 + 565553 = 565720

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 565,720 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 565720 first appears in π at position 156,247 of the decimal expansion (the 156,247ordinal-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.
