Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171148, here are decompositions:

  • 17 + 171131 = 171148
  • 71 + 171077 = 171148
  • 101 + 171047 = 171148
  • 191 + 170957 = 171148
  • 227 + 170921 = 171148
  • 311 + 170837 = 171148
  • 347 + 170801 = 171148
  • 389 + 170759 = 171148

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 171,148 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 171148 first appears in π at position 306,466 of the decimal expansion (the 306,466ordinal-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.
