Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178492, here are decompositions:

  • 3 + 178489 = 178492
  • 5 + 178487 = 178492
  • 11 + 178481 = 178492
  • 23 + 178469 = 178492
  • 53 + 178439 = 178492
  • 89 + 178403 = 178492
  • 131 + 178361 = 178492
  • 191 + 178301 = 178492

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 178,492 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 178492 first appears in π at position 722,044 of the decimal expansion (the 722,044ordinal-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.
