Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3722, here are decompositions:

3 + 3719 = 3722
13 + 3709 = 3722
31 + 3691 = 3722
79 + 3643 = 3722
109 + 3613 = 3722
139 + 3583 = 3722
151 + 3571 = 3722
163 + 3559 = 3722

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3722 first appears in π at position 2,138 of the decimal expansion (the 2,138ordinal-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.
