Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149340, here are decompositions:

  • 7 + 149333 = 149340
  • 17 + 149323 = 149340
  • 31 + 149309 = 149340
  • 43 + 149297 = 149340
  • 53 + 149287 = 149340
  • 71 + 149269 = 149340
  • 83 + 149257 = 149340
  • 89 + 149251 = 149340

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 149,340 and was likely granted around 1873.

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

Position in π

The digit sequence 149340 first appears in π at position 49,763 of the decimal expansion (the 49,763ordinal-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.
