Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166230, here are decompositions:

  • 11 + 166219 = 166230
  • 23 + 166207 = 166230
  • 41 + 166189 = 166230
  • 47 + 166183 = 166230
  • 61 + 166169 = 166230
  • 73 + 166157 = 166230
  • 79 + 166151 = 166230
  • 83 + 166147 = 166230

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 166,230 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 166230 first appears in π at position 615,987 of the decimal expansion (the 615,987ordinal-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.
