Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7922, here are decompositions:

3 + 7919 = 7922
43 + 7879 = 7922
163 + 7759 = 7922
181 + 7741 = 7922
199 + 7723 = 7922
223 + 7699 = 7922
241 + 7681 = 7922
283 + 7639 = 7922

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7922 first appears in π at position 685 of the decimal expansion (the 685ordinal-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.
