Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7130, here are decompositions:

3 + 7127 = 7130
61 + 7069 = 7130
73 + 7057 = 7130
103 + 7027 = 7130
139 + 6991 = 7130
163 + 6967 = 7130
181 + 6949 = 7130
223 + 6907 = 7130

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7130 first appears in π at position 743 of the decimal expansion (the 743ordinal-suffix:rd 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.
