Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186584, here are decompositions:

  • 3 + 186581 = 186584
  • 103 + 186481 = 186584
  • 193 + 186391 = 186584
  • 241 + 186343 = 186584
  • 283 + 186301 = 186584
  • 313 + 186271 = 186584
  • 331 + 186253 = 186584
  • 337 + 186247 = 186584

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 186,584 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 186584 first appears in π at position 16,532 of the decimal expansion (the 16,532ordinal-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.
