Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166200, here are decompositions:

  • 11 + 166189 = 166200
  • 17 + 166183 = 166200
  • 31 + 166169 = 166200
  • 43 + 166157 = 166200
  • 53 + 166147 = 166200
  • 101 + 166099 = 166200
  • 137 + 166063 = 166200
  • 157 + 166043 = 166200

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 166,200 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 166200 first appears in π at position 601,386 of the decimal expansion (the 601,386ordinal-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.
