Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519724, here are decompositions:

  • 11 + 519713 = 519724
  • 41 + 519683 = 519724
  • 113 + 519611 = 519724
  • 137 + 519587 = 519724
  • 173 + 519551 = 519724
  • 197 + 519527 = 519724
  • 311 + 519413 = 519724
  • 353 + 519371 = 519724

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 519,724 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 519724 first appears in π at position 468,087 of the decimal expansion (the 468,087ordinal-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.
