Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105646, here are decompositions:

  • 83 + 105563 = 105646
  • 89 + 105557 = 105646
  • 113 + 105533 = 105646
  • 137 + 105509 = 105646
  • 179 + 105467 = 105646
  • 197 + 105449 = 105646
  • 239 + 105407 = 105646
  • 257 + 105389 = 105646

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 105,646 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 105646 first appears in π at position 282,553 of the decimal expansion (the 282,553ordinal-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.
