Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183620, here are decompositions:

  • 43 + 183577 = 183620
  • 97 + 183523 = 183620
  • 109 + 183511 = 183620
  • 181 + 183439 = 183620
  • 223 + 183397 = 183620
  • 271 + 183349 = 183620
  • 277 + 183343 = 183620
  • 313 + 183307 = 183620

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 183,620 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 183620 first appears in π at position 177,237 of the decimal expansion (the 177,237ordinal-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.
