Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136218, here are decompositions:

  • 11 + 136207 = 136218
  • 29 + 136189 = 136218
  • 41 + 136177 = 136218
  • 79 + 136139 = 136218
  • 107 + 136111 = 136218
  • 149 + 136069 = 136218
  • 151 + 136067 = 136218
  • 191 + 136027 = 136218

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 136,218 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 136218 first appears in π at position 32,162 of the decimal expansion (the 32,162ordinal-suffix:nd 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.
