Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1510, here are decompositions:

11 + 1499 = 1510
17 + 1493 = 1510
23 + 1487 = 1510
29 + 1481 = 1510
59 + 1451 = 1510
71 + 1439 = 1510
83 + 1427 = 1510
101 + 1409 = 1510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1510 first appears in π at position 10,238 of the decimal expansion (the 10,238ordinal-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.
