Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137384, here are decompositions:

  • 31 + 137353 = 137384
  • 43 + 137341 = 137384
  • 193 + 137191 = 137384
  • 241 + 137143 = 137384
  • 307 + 137077 = 137384
  • 397 + 136987 = 137384
  • 421 + 136963 = 137384
  • 433 + 136951 = 137384

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 137,384 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 137384 first appears in π at position 55,351 of the decimal expansion (the 55,351ordinal-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.
