Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187078, here are decompositions:

  • 5 + 187073 = 187078
  • 11 + 187067 = 187078
  • 29 + 187049 = 187078
  • 131 + 186947 = 187078
  • 317 + 186761 = 187078
  • 389 + 186689 = 187078
  • 431 + 186647 = 187078
  • 449 + 186629 = 187078

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 187,078 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 187078 first appears in π at position 880,751 of the decimal expansion (the 880,751ordinal-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.
