Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136784, here are decompositions:

  • 7 + 136777 = 136784
  • 31 + 136753 = 136784
  • 73 + 136711 = 136784
  • 127 + 136657 = 136784
  • 163 + 136621 = 136784
  • 181 + 136603 = 136784
  • 211 + 136573 = 136784
  • 283 + 136501 = 136784

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 136,784 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 136784 first appears in π at position 726,933 of the decimal expansion (the 726,933ordinal-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.
