Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172342, here are decompositions:

  • 11 + 172331 = 172342
  • 29 + 172313 = 172342
  • 59 + 172283 = 172342
  • 83 + 172259 = 172342
  • 173 + 172169 = 172342
  • 263 + 172079 = 172342
  • 293 + 172049 = 172342
  • 311 + 172031 = 172342

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 172,342 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 172342 first appears in π at position 148,392 of the decimal expansion (the 148,392ordinal-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.
