Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123038, here are decompositions:

  • 7 + 123031 = 123038
  • 31 + 123007 = 123038
  • 37 + 123001 = 123038
  • 67 + 122971 = 123038
  • 109 + 122929 = 123038
  • 151 + 122887 = 123038
  • 199 + 122839 = 123038
  • 211 + 122827 = 123038

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 123,038 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 123038 first appears in π at position 418,723 of the decimal expansion (the 418,723ordinal-suffix:rd 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.
