Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108540, here are decompositions:

  • 7 + 108533 = 108540
  • 11 + 108529 = 108540
  • 23 + 108517 = 108540
  • 37 + 108503 = 108540
  • 41 + 108499 = 108540
  • 43 + 108497 = 108540
  • 79 + 108461 = 108540
  • 83 + 108457 = 108540

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 108,540 and was likely granted around 1870.

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

Position in π

The digit sequence 108540 first appears in π at position 882,505 of the decimal expansion (the 882,505ordinal-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.
