Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183540, here are decompositions:

  • 13 + 183527 = 183540
  • 17 + 183523 = 183540
  • 29 + 183511 = 183540
  • 31 + 183509 = 183540
  • 37 + 183503 = 183540
  • 41 + 183499 = 183540
  • 43 + 183497 = 183540
  • 53 + 183487 = 183540

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 183,540 and was likely granted around 1875.

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

Position in π

The digit sequence 183540 first appears in π at position 424,357 of the decimal expansion (the 424,357ordinal-suffix:th 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.
