Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180836, here are decompositions:

  • 37 + 180799 = 180836
  • 43 + 180793 = 180836
  • 157 + 180679 = 180836
  • 373 + 180463 = 180836
  • 457 + 180379 = 180836
  • 499 + 180337 = 180836
  • 547 + 180289 = 180836
  • 577 + 180259 = 180836

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 180,836 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 180836 first appears in π at position 552,650 of the decimal expansion (the 552,650ordinal-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.
