Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162918, here are decompositions:

  • 11 + 162907 = 162918
  • 17 + 162901 = 162918
  • 29 + 162889 = 162918
  • 37 + 162881 = 162918
  • 59 + 162859 = 162918
  • 71 + 162847 = 162918
  • 79 + 162839 = 162918
  • 89 + 162829 = 162918

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 162,918 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 162918 first appears in π at position 70,538 of the decimal expansion (the 70,538ordinal-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.
