Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513646, here are decompositions:

  • 5 + 513641 = 513646
  • 53 + 513593 = 513646
  • 113 + 513533 = 513646
  • 137 + 513509 = 513646
  • 167 + 513479 = 513646
  • 173 + 513473 = 513646
  • 227 + 513419 = 513646
  • 239 + 513407 = 513646

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 513,646 and was likely granted around 1893.

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

Position in π

The digit sequence 513646 first appears in π at position 937,027 of the decimal expansion (the 937,027ordinal-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.
