Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166822, here are decompositions:

  • 23 + 166799 = 166822
  • 41 + 166781 = 166822
  • 83 + 166739 = 166822
  • 179 + 166643 = 166822
  • 191 + 166631 = 166822
  • 251 + 166571 = 166822
  • 281 + 166541 = 166822
  • 419 + 166403 = 166822

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 166,822 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 166822 first appears in π at position 997,506 of the decimal expansion (the 997,506ordinal-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.
