Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180194, here are decompositions:

  • 13 + 180181 = 180194
  • 97 + 180097 = 180194
  • 151 + 180043 = 180194
  • 193 + 180001 = 180194
  • 241 + 179953 = 180194
  • 271 + 179923 = 180194
  • 277 + 179917 = 180194
  • 367 + 179827 = 180194

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 180,194 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 180194 first appears in π at position 273,377 of the decimal expansion (the 273,377ordinal-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.
