Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153170, here are decompositions:

  • 19 + 153151 = 153170
  • 37 + 153133 = 153170
  • 97 + 153073 = 153170
  • 103 + 153067 = 153170
  • 181 + 152989 = 153170
  • 211 + 152959 = 153170
  • 223 + 152947 = 153170
  • 229 + 152941 = 153170

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 153,170 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 153170 first appears in π at position 31,035 of the decimal expansion (the 31,035ordinal-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.
