Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105560, here are decompositions:

  • 3 + 105557 = 105560
  • 19 + 105541 = 105560
  • 31 + 105529 = 105560
  • 43 + 105517 = 105560
  • 61 + 105499 = 105560
  • 163 + 105397 = 105560
  • 181 + 105379 = 105560
  • 193 + 105367 = 105560

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 105,560 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 105560 first appears in π at position 625,852 of the decimal expansion (the 625,852ordinal-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.
