Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178260, here are decompositions:

  • 11 + 178249 = 178260
  • 13 + 178247 = 178260
  • 29 + 178231 = 178260
  • 37 + 178223 = 178260
  • 53 + 178207 = 178260
  • 73 + 178187 = 178260
  • 109 + 178151 = 178260
  • 157 + 178103 = 178260

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 178,260 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 178260 first appears in π at position 29,979 of the decimal expansion (the 29,979ordinal-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.
