Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178274, here are decompositions:

  • 13 + 178261 = 178274
  • 43 + 178231 = 178274
  • 67 + 178207 = 178274
  • 157 + 178117 = 178274
  • 181 + 178093 = 178274
  • 307 + 177967 = 178274
  • 331 + 177943 = 178274
  • 367 + 177907 = 178274

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 178,274 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 178274 first appears in π at position 332,342 of the decimal expansion (the 332,342ordinal-suffix:nd 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.
