Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166700, here are decompositions:

  • 7 + 166693 = 166700
  • 31 + 166669 = 166700
  • 43 + 166657 = 166700
  • 73 + 166627 = 166700
  • 97 + 166603 = 166700
  • 103 + 166597 = 166700
  • 139 + 166561 = 166700
  • 229 + 166471 = 166700

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 166,700 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 166700 first appears in π at position 734,708 of the decimal expansion (the 734,708ordinal-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.
