Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186284, here are decompositions:

  • 13 + 186271 = 186284
  • 31 + 186253 = 186284
  • 37 + 186247 = 186284
  • 73 + 186211 = 186284
  • 97 + 186187 = 186284
  • 127 + 186157 = 186284
  • 181 + 186103 = 186284
  • 271 + 186013 = 186284

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 186,284 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 186284 first appears in π at position 51,598 of the decimal expansion (the 51,598ordinal-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.
