Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185184, here are decompositions:

  • 7 + 185177 = 185184
  • 17 + 185167 = 185184
  • 23 + 185161 = 185184
  • 31 + 185153 = 185184
  • 47 + 185137 = 185184
  • 53 + 185131 = 185184
  • 61 + 185123 = 185184
  • 107 + 185077 = 185184

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 185,184 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 185184 first appears in π at position 45,339 of the decimal expansion (the 45,339ordinal-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.
