Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180254, here are decompositions:

  • 7 + 180247 = 180254
  • 13 + 180241 = 180254
  • 43 + 180211 = 180254
  • 73 + 180181 = 180254
  • 157 + 180097 = 180254
  • 181 + 180073 = 180254
  • 211 + 180043 = 180254
  • 307 + 179947 = 180254

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 180,254 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 180254 first appears in π at position 968,004 of the decimal expansion (the 968,004ordinal-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.
