Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180492, here are decompositions:

  • 19 + 180473 = 180492
  • 29 + 180463 = 180492
  • 73 + 180419 = 180492
  • 79 + 180413 = 180492
  • 101 + 180391 = 180492
  • 113 + 180379 = 180492
  • 131 + 180361 = 180492
  • 181 + 180311 = 180492

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 180,492 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 180492 first appears in π at position 766,232 of the decimal expansion (the 766,232ordinal-suffix:nd 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.
