Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518164, here are decompositions:

  • 5 + 518159 = 518164
  • 11 + 518153 = 518164
  • 41 + 518123 = 518164
  • 107 + 518057 = 518164
  • 173 + 517991 = 518164
  • 197 + 517967 = 518164
  • 233 + 517931 = 518164
  • 263 + 517901 = 518164

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 518,164 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 518164 first appears in π at position 448,507 of the decimal expansion (the 448,507ordinal-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.
