Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519646, here are decompositions:

  • 3 + 519643 = 519646
  • 59 + 519587 = 519646
  • 107 + 519539 = 519646
  • 137 + 519509 = 519646
  • 233 + 519413 = 519646
  • 263 + 519383 = 519646
  • 293 + 519353 = 519646
  • 359 + 519287 = 519646

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 519,646 and was likely granted around 1894.

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

Position in π

The digit sequence 519646 first appears in π at position 962,334 of the decimal expansion (the 962,334ordinal-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.
