Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518384, here are decompositions:

  • 43 + 518341 = 518384
  • 73 + 518311 = 518384
  • 151 + 518233 = 518384
  • 193 + 518191 = 518384
  • 271 + 518113 = 518384
  • 283 + 518101 = 518384
  • 337 + 518047 = 518384
  • 367 + 518017 = 518384

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 518,384 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 518384 first appears in π at position 596,919 of the decimal expansion (the 596,919ordinal-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.
