Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178324, here are decompositions:

  • 17 + 178307 = 178324
  • 23 + 178301 = 178324
  • 101 + 178223 = 178324
  • 137 + 178187 = 178324
  • 173 + 178151 = 178324
  • 197 + 178127 = 178324
  • 233 + 178091 = 178324
  • 257 + 178067 = 178324

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 178,324 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 178324 first appears in π at position 518,460 of the decimal expansion (the 518,460ordinal-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.
