Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180536, here are decompositions:

  • 3 + 180533 = 180536
  • 73 + 180463 = 180536
  • 157 + 180379 = 180536
  • 199 + 180337 = 180536
  • 229 + 180307 = 180536
  • 277 + 180259 = 180536
  • 439 + 180097 = 180536
  • 463 + 180073 = 180536

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 180,536 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 180536 first appears in π at position 620,331 of the decimal expansion (the 620,331ordinal-suffix:st 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.
