Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565442, here are decompositions:

  • 13 + 565429 = 565442
  • 61 + 565381 = 565442
  • 109 + 565333 = 565442
  • 139 + 565303 = 565442
  • 181 + 565261 = 565442
  • 271 + 565171 = 565442
  • 331 + 565111 = 565442
  • 373 + 565069 = 565442

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 565,442 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 565442 first appears in π at position 219,407 of the decimal expansion (the 219,407ordinal-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.
