Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178330, here are decompositions:

  • 3 + 178327 = 178330
  • 23 + 178307 = 178330
  • 29 + 178301 = 178330
  • 41 + 178289 = 178330
  • 71 + 178259 = 178330
  • 83 + 178247 = 178330
  • 107 + 178223 = 178330
  • 179 + 178151 = 178330

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 178,330 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 178330 first appears in π at position 596,707 of the decimal expansion (the 596,707ordinal-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.
