Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180238, here are decompositions:

  • 5 + 180233 = 180238
  • 17 + 180221 = 180238
  • 59 + 180179 = 180238
  • 101 + 180137 = 180238
  • 167 + 180071 = 180238
  • 239 + 179999 = 180238
  • 257 + 179981 = 180238
  • 269 + 179969 = 180238

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 180,238 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 180238 first appears in π at position 25,085 of the decimal expansion (the 25,085ordinal-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.
