Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167228, here are decompositions:

  • 7 + 167221 = 167228
  • 31 + 167197 = 167228
  • 37 + 167191 = 167228
  • 79 + 167149 = 167228
  • 109 + 167119 = 167228
  • 151 + 167077 = 167228
  • 157 + 167071 = 167228
  • 181 + 167047 = 167228

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 167,228 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 167228 first appears in π at position 101,213 of the decimal expansion (the 101,213ordinal-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.
