Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105564, here are decompositions:

  • 7 + 105557 = 105564
  • 23 + 105541 = 105564
  • 31 + 105533 = 105564
  • 37 + 105527 = 105564
  • 47 + 105517 = 105564
  • 61 + 105503 = 105564
  • 73 + 105491 = 105564
  • 97 + 105467 = 105564

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 105,564 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 105564 first appears in π at position 591,907 of the decimal expansion (the 591,907ordinal-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.
