Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178282, here are decompositions:

  • 23 + 178259 = 178282
  • 59 + 178223 = 178282
  • 113 + 178169 = 178282
  • 131 + 178151 = 178282
  • 179 + 178103 = 178282
  • 191 + 178091 = 178282
  • 281 + 178001 = 178282
  • 353 + 177929 = 178282

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 178,282 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 178282 first appears in π at position 118,003 of the decimal expansion (the 118,003ordinal-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.
