Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178004, here are decompositions:

  • 3 + 178001 = 178004
  • 37 + 177967 = 178004
  • 61 + 177943 = 178004
  • 97 + 177907 = 178004
  • 163 + 177841 = 178004
  • 181 + 177823 = 178004
  • 193 + 177811 = 178004
  • 241 + 177763 = 178004

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 178,004 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 178004 first appears in π at position 880,866 of the decimal expansion (the 880,866ordinal-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.
