Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166306, here are decompositions:

  • 3 + 166303 = 166306
  • 5 + 166301 = 166306
  • 17 + 166289 = 166306
  • 47 + 166259 = 166306
  • 59 + 166247 = 166306
  • 137 + 166169 = 166306
  • 149 + 166157 = 166306
  • 263 + 166043 = 166306

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 166,306 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 166306 first appears in π at position 99,848 of the decimal expansion (the 99,848ordinal-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.
