Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160218, here are decompositions:

  • 11 + 160207 = 160218
  • 17 + 160201 = 160218
  • 59 + 160159 = 160218
  • 101 + 160117 = 160218
  • 127 + 160091 = 160218
  • 131 + 160087 = 160218
  • 137 + 160081 = 160218
  • 139 + 160079 = 160218

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 160,218 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 160218 first appears in π at position 295,335 of the decimal expansion (the 295,335ordinal-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.
