Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186994, here are decompositions:

  • 47 + 186947 = 186994
  • 233 + 186761 = 186994
  • 251 + 186743 = 186994
  • 293 + 186701 = 186994
  • 347 + 186647 = 186994
  • 443 + 186551 = 186994
  • 557 + 186437 = 186994
  • 617 + 186377 = 186994

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 186,994 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 186994 first appears in π at position 550,842 of the decimal expansion (the 550,842ordinal-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.
