Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105118, here are decompositions:

  • 11 + 105107 = 105118
  • 47 + 105071 = 105118
  • 131 + 104987 = 105118
  • 227 + 104891 = 105118
  • 239 + 104879 = 105118
  • 269 + 104849 = 105118
  • 317 + 104801 = 105118
  • 359 + 104759 = 105118

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 105,118 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 105118 first appears in π at position 442 of the decimal expansion (the 442ordinal-suffix:nd 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.
