Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162108, here are decompositions:

  • 17 + 162091 = 162108
  • 29 + 162079 = 162108
  • 97 + 162011 = 162108
  • 101 + 162007 = 162108
  • 109 + 161999 = 162108
  • 131 + 161977 = 162108
  • 137 + 161971 = 162108
  • 139 + 161969 = 162108

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 162,108 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 162108 first appears in π at position 700,001 of the decimal expansion (the 700,001ordinal-suffix:st 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.
