Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11216, here are decompositions:

  • 3 + 11213 = 11216
  • 19 + 11197 = 11216
  • 43 + 11173 = 11216
  • 67 + 11149 = 11216
  • 97 + 11119 = 11216
  • 103 + 11113 = 11216
  • 157 + 11059 = 11216
  • 223 + 10993 = 11216

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11216 first appears in π at position 115,322 of the decimal expansion (the 115,322ordinal-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.
