Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519128, here are decompositions:

  • 7 + 519121 = 519128
  • 31 + 519097 = 519128
  • 37 + 519091 = 519128
  • 61 + 519067 = 519128
  • 97 + 519031 = 519128
  • 139 + 518989 = 519128
  • 349 + 518779 = 519128
  • 367 + 518761 = 519128

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 519,128 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 519128 first appears in π at position 444,777 of the decimal expansion (the 444,777ordinal-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.
