Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166040, here are decompositions:

  • 13 + 166027 = 166040
  • 19 + 166021 = 166040
  • 79 + 165961 = 166040
  • 109 + 165931 = 166040
  • 139 + 165901 = 166040
  • 157 + 165883 = 166040
  • 163 + 165877 = 166040
  • 211 + 165829 = 166040

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 166,040 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 166040 first appears in π at position 968,751 of the decimal expansion (the 968,751ordinal-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.
