Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19648, here are decompositions:

71 + 19577 = 19648
89 + 19559 = 19648
107 + 19541 = 19648
179 + 19469 = 19648
191 + 19457 = 19648
227 + 19421 = 19648
257 + 19391 = 19648
269 + 19379 = 19648

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19648 first appears in π at position 12,209 of the decimal expansion (the 12,209ordinal-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.
