Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518022, here are decompositions:

  • 5 + 518017 = 518022
  • 23 + 517999 = 518022
  • 31 + 517991 = 518022
  • 41 + 517981 = 518022
  • 73 + 517949 = 518022
  • 103 + 517919 = 518022
  • 149 + 517873 = 518022
  • 191 + 517831 = 518022

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 518,022 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 518022 first appears in π at position 75,757 of the decimal expansion (the 75,757ordinal-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.
