Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163756, here are decompositions:

  • 3 + 163753 = 163756
  • 23 + 163733 = 163756
  • 59 + 163697 = 163756
  • 83 + 163673 = 163756
  • 113 + 163643 = 163756
  • 239 + 163517 = 163756
  • 269 + 163487 = 163756
  • 347 + 163409 = 163756

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 163,756 and was likely granted around 1874.

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

Position in π

The digit sequence 163756 first appears in π at position 284,686 of the decimal expansion (the 284,686ordinal-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.
