Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180746, here are decompositions:

  • 67 + 180679 = 180746
  • 79 + 180667 = 180746
  • 199 + 180547 = 180746
  • 283 + 180463 = 180746
  • 367 + 180379 = 180746
  • 409 + 180337 = 180746
  • 439 + 180307 = 180746
  • 457 + 180289 = 180746

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 180,746 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 180746 first appears in π at position 296,544 of the decimal expansion (the 296,544ordinal-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.
