Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11828, here are decompositions:

  • 7 + 11821 = 11828
  • 97 + 11731 = 11828
  • 109 + 11719 = 11828
  • 127 + 11701 = 11828
  • 139 + 11689 = 11828
  • 151 + 11677 = 11828
  • 211 + 11617 = 11828
  • 241 + 11587 = 11828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11828 first appears in π at position 163,544 of the decimal expansion (the 163,544ordinal-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.
