Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518412, here are decompositions:

  • 23 + 518389 = 518412
  • 71 + 518341 = 518412
  • 101 + 518311 = 518412
  • 113 + 518299 = 518412
  • 151 + 518261 = 518412
  • 163 + 518249 = 518412
  • 173 + 518239 = 518412
  • 179 + 518233 = 518412

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 518,412 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 518412 first appears in π at position 322,014 of the decimal expansion (the 322,014ordinal-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.
