Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7618, here are decompositions:

11 + 7607 = 7618
29 + 7589 = 7618
41 + 7577 = 7618
59 + 7559 = 7618
71 + 7547 = 7618
89 + 7529 = 7618
101 + 7517 = 7618
131 + 7487 = 7618

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7618 first appears in π at position 3,547 of the decimal expansion (the 3,547ordinal-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.
