Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105194, here are decompositions:

  • 97 + 105097 = 105194
  • 157 + 105037 = 105194
  • 163 + 105031 = 105194
  • 223 + 104971 = 105194
  • 241 + 104953 = 105194
  • 277 + 104917 = 105194
  • 283 + 104911 = 105194
  • 367 + 104827 = 105194

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 105,194 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 105194 first appears in π at position 709,045 of the decimal expansion (the 709,045ordinal-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.
