Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185422, here are decompositions:

  • 53 + 185369 = 185422
  • 59 + 185363 = 185422
  • 113 + 185309 = 185422
  • 131 + 185291 = 185422
  • 179 + 185243 = 185422
  • 233 + 185189 = 185422
  • 239 + 185183 = 185422
  • 269 + 185153 = 185422

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 185,422 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 185422 first appears in π at position 493,308 of the decimal expansion (the 493,308ordinal-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.
