Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519786, here are decompositions:

  • 17 + 519769 = 519786
  • 53 + 519733 = 519786
  • 73 + 519713 = 519786
  • 83 + 519703 = 519786
  • 103 + 519683 = 519786
  • 139 + 519647 = 519786
  • 167 + 519619 = 519786
  • 199 + 519587 = 519786

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 519,786 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 519786 first appears in π at position 258,099 of the decimal expansion (the 258,099ordinal-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.
