Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160880, here are decompositions:

  • 3 + 160877 = 160880
  • 19 + 160861 = 160880
  • 67 + 160813 = 160880
  • 73 + 160807 = 160880
  • 127 + 160753 = 160880
  • 157 + 160723 = 160880
  • 193 + 160687 = 160880
  • 199 + 160681 = 160880

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 160,880 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 160880 first appears in π at position 84,915 of the decimal expansion (the 84,915ordinal-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.
