Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105600, here are decompositions:

  • 37 + 105563 = 105600
  • 43 + 105557 = 105600
  • 59 + 105541 = 105600
  • 67 + 105533 = 105600
  • 71 + 105529 = 105600
  • 73 + 105527 = 105600
  • 83 + 105517 = 105600
  • 97 + 105503 = 105600

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 105,600 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 105600 first appears in π at position 381,822 of the decimal expansion (the 381,822ordinal-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.
