Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178894, here are decompositions:

  • 5 + 178889 = 178894
  • 17 + 178877 = 178894
  • 41 + 178853 = 178894
  • 101 + 178793 = 178894
  • 113 + 178781 = 178894
  • 137 + 178757 = 178894
  • 197 + 178697 = 178894
  • 251 + 178643 = 178894

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 178,894 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 178894 first appears in π at position 441,671 of the decimal expansion (the 441,671ordinal-suffix:st 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.
