Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123228, here are decompositions:

  • 11 + 123217 = 123228
  • 19 + 123209 = 123228
  • 37 + 123191 = 123228
  • 59 + 123169 = 123228
  • 101 + 123127 = 123228
  • 107 + 123121 = 123228
  • 137 + 123091 = 123228
  • 151 + 123077 = 123228

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 123,228 and was likely granted around 1871.

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

Position in π

The digit sequence 123228 first appears in π at position 880,284 of the decimal expansion (the 880,284ordinal-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.
