Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113780, here are decompositions:

  • 3 + 113777 = 113780
  • 19 + 113761 = 113780
  • 31 + 113749 = 113780
  • 61 + 113719 = 113780
  • 97 + 113683 = 113780
  • 157 + 113623 = 113780
  • 223 + 113557 = 113780
  • 241 + 113539 = 113780

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 113,780 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 113780 first appears in π at position 633,526 of the decimal expansion (the 633,526ordinal-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.
