Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166908, here are decompositions:

  • 37 + 166871 = 166908
  • 41 + 166867 = 166908
  • 47 + 166861 = 166908
  • 59 + 166849 = 166908
  • 61 + 166847 = 166908
  • 67 + 166841 = 166908
  • 101 + 166807 = 166908
  • 109 + 166799 = 166908

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 166,908 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 166908 first appears in π at position 228,049 of the decimal expansion (the 228,049ordinal-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.
