Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178292, here are decompositions:

  • 3 + 178289 = 178292
  • 31 + 178261 = 178292
  • 43 + 178249 = 178292
  • 61 + 178231 = 178292
  • 109 + 178183 = 178292
  • 151 + 178141 = 178292
  • 199 + 178093 = 178292
  • 223 + 178069 = 178292

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 178,292 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 178292 first appears in π at position 424,523 of the decimal expansion (the 424,523ordinal-suffix:rd 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.
