Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18232, here are decompositions:

  • 3 + 18229 = 18232
  • 41 + 18191 = 18232
  • 83 + 18149 = 18232
  • 89 + 18143 = 18232
  • 101 + 18131 = 18232
  • 113 + 18119 = 18232
  • 173 + 18059 = 18232
  • 191 + 18041 = 18232

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18232 first appears in π at position 27,038 of the decimal expansion (the 27,038ordinal-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.
