Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1748, here are decompositions:

7 + 1741 = 1748
79 + 1669 = 1748
127 + 1621 = 1748
139 + 1609 = 1748
151 + 1597 = 1748
181 + 1567 = 1748
199 + 1549 = 1748
277 + 1471 = 1748

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1748 first appears in π at position 319 of the decimal expansion (the 319ordinal-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.
