Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518674, here are decompositions:

  • 17 + 518657 = 518674
  • 53 + 518621 = 518674
  • 131 + 518543 = 518674
  • 227 + 518447 = 518674
  • 257 + 518417 = 518674
  • 263 + 518411 = 518674
  • 347 + 518327 = 518674
  • 383 + 518291 = 518674

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 518,674 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 518674 first appears in π at position 209,762 of the decimal expansion (the 209,762ordinal-suffix:nd 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.
