Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12318, here are decompositions:

  • 17 + 12301 = 12318
  • 29 + 12289 = 12318
  • 37 + 12281 = 12318
  • 41 + 12277 = 12318
  • 67 + 12251 = 12318
  • 79 + 12239 = 12318
  • 107 + 12211 = 12318
  • 157 + 12161 = 12318

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12318 first appears in π at position 16,943 of the decimal expansion (the 16,943ordinal-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.
