Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105566, here are decompositions:

  • 3 + 105563 = 105566
  • 37 + 105529 = 105566
  • 67 + 105499 = 105566
  • 193 + 105373 = 105566
  • 199 + 105367 = 105566
  • 229 + 105337 = 105566
  • 313 + 105253 = 105566
  • 337 + 105229 = 105566

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 105,566 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 105566 first appears in π at position 402,524 of the decimal expansion (the 402,524ordinal-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.
