Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565490, here are decompositions:

  • 7 + 565483 = 565490
  • 61 + 565429 = 565490
  • 97 + 565393 = 565490
  • 103 + 565387 = 565490
  • 109 + 565381 = 565490
  • 157 + 565333 = 565490
  • 229 + 565261 = 565490
  • 283 + 565207 = 565490

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 565,490 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 565490 first appears in π at position 451,131 of the decimal expansion (the 451,131ordinal-suffix:st 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.
