Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518912, here are decompositions:

  • 19 + 518893 = 518912
  • 103 + 518809 = 518912
  • 109 + 518803 = 518912
  • 151 + 518761 = 518912
  • 223 + 518689 = 518912
  • 379 + 518533 = 518912
  • 439 + 518473 = 518912
  • 523 + 518389 = 518912

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 518,912 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 518912 first appears in π at position 855,676 of the decimal expansion (the 855,676ordinal-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.
