Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184280, here are decompositions:

  • 7 + 184273 = 184280
  • 127 + 184153 = 184280
  • 163 + 184117 = 184280
  • 193 + 184087 = 184280
  • 199 + 184081 = 184280
  • 223 + 184057 = 184280
  • 241 + 184039 = 184280
  • 277 + 184003 = 184280

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 184,280 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 184280 first appears in π at position 260,347 of the decimal expansion (the 260,347ordinal-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.
