Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11172, here are decompositions:

  • 11 + 11161 = 11172
  • 13 + 11159 = 11172
  • 23 + 11149 = 11172
  • 41 + 11131 = 11172
  • 53 + 11119 = 11172
  • 59 + 11113 = 11172
  • 79 + 11093 = 11172
  • 89 + 11083 = 11172

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11172 first appears in π at position 6,803 of the decimal expansion (the 6,803ordinal-suffix:rd 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.
