Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166270, here are decompositions:

  • 11 + 166259 = 166270
  • 23 + 166247 = 166270
  • 101 + 166169 = 166270
  • 113 + 166157 = 166270
  • 227 + 166043 = 166270
  • 239 + 166031 = 166270
  • 257 + 166013 = 166270
  • 383 + 165887 = 166270

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 166,270 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 166270 first appears in π at position 93,848 of the decimal expansion (the 93,848ordinal-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.
