Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519138, here are decompositions:

  • 7 + 519131 = 519138
  • 17 + 519121 = 519138
  • 19 + 519119 = 519138
  • 31 + 519107 = 519138
  • 41 + 519097 = 519138
  • 47 + 519091 = 519138
  • 71 + 519067 = 519138
  • 101 + 519037 = 519138

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 519,138 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 519138 first appears in π at position 337,286 of the decimal expansion (the 337,286ordinal-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.
