Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166830, here are decompositions:

  • 7 + 166823 = 166830
  • 23 + 166807 = 166830
  • 31 + 166799 = 166830
  • 47 + 166783 = 166830
  • 89 + 166741 = 166830
  • 107 + 166723 = 166830
  • 127 + 166703 = 166830
  • 137 + 166693 = 166830

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 166,830 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 166830 first appears in π at position 814,887 of the decimal expansion (the 814,887ordinal-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.
