Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171100, here are decompositions:

  • 23 + 171077 = 171100
  • 47 + 171053 = 171100
  • 53 + 171047 = 171100
  • 71 + 171029 = 171100
  • 173 + 170927 = 171100
  • 179 + 170921 = 171100
  • 227 + 170873 = 171100
  • 257 + 170843 = 171100

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 171,100 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 171100 first appears in π at position 816,234 of the decimal expansion (the 816,234ordinal-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.
