Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180768, here are decompositions:

  • 17 + 180751 = 180768
  • 19 + 180749 = 180768
  • 37 + 180731 = 180768
  • 67 + 180701 = 180768
  • 89 + 180679 = 180768
  • 101 + 180667 = 180768
  • 139 + 180629 = 180768
  • 151 + 180617 = 180768

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 180,768 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 180768 first appears in π at position 567,928 of the decimal expansion (the 567,928ordinal-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.
