Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3724, here are decompositions:

5 + 3719 = 3724
23 + 3701 = 3724
47 + 3677 = 3724
53 + 3671 = 3724
101 + 3623 = 3724
107 + 3617 = 3724
131 + 3593 = 3724
167 + 3557 = 3724

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3724 first appears in π at position 300 of the decimal expansion (the 300ordinal-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.
