Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1536, here are decompositions:

5 + 1531 = 1536
13 + 1523 = 1536
37 + 1499 = 1536
43 + 1493 = 1536
47 + 1489 = 1536
53 + 1483 = 1536
83 + 1453 = 1536
89 + 1447 = 1536

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1536 first appears in π at position 344 of the decimal expansion (the 344ordinal-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.
