Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178892, here are decompositions:

  • 3 + 178889 = 178892
  • 19 + 178873 = 178892
  • 61 + 178831 = 178892
  • 73 + 178819 = 178892
  • 79 + 178813 = 178892
  • 139 + 178753 = 178892
  • 199 + 178693 = 178892
  • 211 + 178681 = 178892

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 178,892 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 178892 first appears in π at position 59,582 of the decimal expansion (the 59,582ordinal-suffix:nd 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.
