Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171154, here are decompositions:

  • 23 + 171131 = 171154
  • 101 + 171053 = 171154
  • 107 + 171047 = 171154
  • 131 + 171023 = 171154
  • 197 + 170957 = 171154
  • 227 + 170927 = 171154
  • 233 + 170921 = 171154
  • 281 + 170873 = 171154

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 171,154 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 171154 first appears in π at position 767,323 of the decimal expansion (the 767,323ordinal-suffix:rd 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.
