Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133918, here are decompositions:

  • 41 + 133877 = 133918
  • 107 + 133811 = 133918
  • 137 + 133781 = 133918
  • 149 + 133769 = 133918
  • 227 + 133691 = 133918
  • 269 + 133649 = 133918
  • 347 + 133571 = 133918
  • 359 + 133559 = 133918

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 133,918 and was likely granted around 1872.

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

Position in π

The digit sequence 133918 first appears in π at position 24,791 of the decimal expansion (the 24,791ordinal-suffix:st 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.
