Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160816, here are decompositions:

  • 3 + 160813 = 160816
  • 59 + 160757 = 160816
  • 107 + 160709 = 160816
  • 167 + 160649 = 160816
  • 179 + 160637 = 160816
  • 197 + 160619 = 160816
  • 233 + 160583 = 160816
  • 263 + 160553 = 160816

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 160,816 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 160816 first appears in π at position 918,584 of the decimal expansion (the 918,584ordinal-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.
