Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168018, here are decompositions:

  • 5 + 168013 = 168018
  • 31 + 167987 = 168018
  • 47 + 167971 = 168018
  • 101 + 167917 = 168018
  • 107 + 167911 = 168018
  • 127 + 167891 = 168018
  • 131 + 167887 = 168018
  • 139 + 167879 = 168018

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 168,018 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 168018 first appears in π at position 38,095 of the decimal expansion (the 38,095ordinal-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.
