Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115648, here are decompositions:

  • 11 + 115637 = 115648
  • 17 + 115631 = 115648
  • 47 + 115601 = 115648
  • 59 + 115589 = 115648
  • 101 + 115547 = 115648
  • 149 + 115499 = 115648
  • 179 + 115469 = 115648
  • 227 + 115421 = 115648

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 115,648 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 115648 first appears in π at position 660,560 of the decimal expansion (the 660,560ordinal-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.
