Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160778, here are decompositions:

  • 67 + 160711 = 160778
  • 97 + 160681 = 160778
  • 109 + 160669 = 160778
  • 127 + 160651 = 160778
  • 139 + 160639 = 160778
  • 151 + 160627 = 160778
  • 157 + 160621 = 160778
  • 199 + 160579 = 160778

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 160,778 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 160778 first appears in π at position 157,513 of the decimal expansion (the 157,513ordinal-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.
