Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105170, here are decompositions:

  • 3 + 105167 = 105170
  • 73 + 105097 = 105170
  • 139 + 105031 = 105170
  • 151 + 105019 = 105170
  • 199 + 104971 = 105170
  • 211 + 104959 = 105170
  • 223 + 104947 = 105170
  • 367 + 104803 = 105170

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 105,170 and was likely granted around 1870.

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

Position in π

The digit sequence 105170 first appears in π at position 436,035 of the decimal expansion (the 436,035ordinal-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.
