Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11250, here are decompositions:

  • 7 + 11243 = 11250
  • 11 + 11239 = 11250
  • 37 + 11213 = 11250
  • 53 + 11197 = 11250
  • 73 + 11177 = 11250
  • 79 + 11171 = 11250
  • 89 + 11161 = 11250
  • 101 + 11149 = 11250

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11250 first appears in π at position 17,865 of the decimal expansion (the 17,865ordinal-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.
