Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519942, here are decompositions:

  • 11 + 519931 = 519942
  • 19 + 519923 = 519942
  • 23 + 519919 = 519942
  • 53 + 519889 = 519942
  • 61 + 519881 = 519942
  • 79 + 519863 = 519942
  • 139 + 519803 = 519942
  • 149 + 519793 = 519942

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 519,942 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 519942 first appears in π at position 270,975 of the decimal expansion (the 270,975ordinal-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.
