Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15198, here are decompositions:

  • 5 + 15193 = 15198
  • 11 + 15187 = 15198
  • 37 + 15161 = 15198
  • 59 + 15139 = 15198
  • 61 + 15137 = 15198
  • 67 + 15131 = 15198
  • 97 + 15101 = 15198
  • 107 + 15091 = 15198

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15198 first appears in π at position 113,562 of the decimal expansion (the 113,562ordinal-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.
