Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519812, here are decompositions:

  • 19 + 519793 = 519812
  • 43 + 519769 = 519812
  • 79 + 519733 = 519812
  • 109 + 519703 = 519812
  • 193 + 519619 = 519812
  • 313 + 519499 = 519812
  • 379 + 519433 = 519812
  • 421 + 519391 = 519812

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 519,812 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 519812 first appears in π at position 576,545 of the decimal expansion (the 576,545ordinal-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.
