Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11188, here are decompositions:

  • 11 + 11177 = 11188
  • 17 + 11171 = 11188
  • 29 + 11159 = 11188
  • 71 + 11117 = 11188
  • 101 + 11087 = 11188
  • 131 + 11057 = 11188
  • 239 + 10949 = 11188
  • 251 + 10937 = 11188

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11188 first appears in π at position 35,161 of the decimal expansion (the 35,161ordinal-suffix:st 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.
