Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15112, here are decompositions:

  • 5 + 15107 = 15112
  • 11 + 15101 = 15112
  • 29 + 15083 = 15112
  • 59 + 15053 = 15112
  • 173 + 14939 = 15112
  • 233 + 14879 = 15112
  • 269 + 14843 = 15112
  • 281 + 14831 = 15112

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15112 first appears in π at position 72,361 of the decimal expansion (the 72,361ordinal-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.
