Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3200, here are decompositions:

13 + 3187 = 3200
19 + 3181 = 3200
31 + 3169 = 3200
37 + 3163 = 3200
79 + 3121 = 3200
139 + 3061 = 3200
151 + 3049 = 3200
163 + 3037 = 3200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3200 first appears in π at position 599 of the decimal expansion (the 599ordinal-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.
