Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162986, here are decompositions:

  • 13 + 162973 = 162986
  • 79 + 162907 = 162986
  • 97 + 162889 = 162986
  • 127 + 162859 = 162986
  • 139 + 162847 = 162986
  • 157 + 162829 = 162986
  • 163 + 162823 = 162986
  • 199 + 162787 = 162986

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 162,986 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 162986 first appears in π at position 374,907 of the decimal expansion (the 374,907ordinal-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.
