Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161792, here are decompositions:

  • 13 + 161779 = 161792
  • 19 + 161773 = 161792
  • 31 + 161761 = 161792
  • 61 + 161731 = 161792
  • 109 + 161683 = 161792
  • 151 + 161641 = 161792
  • 181 + 161611 = 161792
  • 193 + 161599 = 161792

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 161,792 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 161792 first appears in π at position 907,066 of the decimal expansion (the 907,066ordinal-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.
