Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178846, here are decompositions:

  • 29 + 178817 = 178846
  • 47 + 178799 = 178846
  • 53 + 178793 = 178846
  • 89 + 178757 = 178846
  • 149 + 178697 = 178846
  • 233 + 178613 = 178846
  • 359 + 178487 = 178846
  • 443 + 178403 = 178846

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 178,846 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 178846 first appears in π at position 255,895 of the decimal expansion (the 255,895ordinal-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.
