Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51020, here are decompositions:

19 + 51001 = 51020
31 + 50989 = 51020
97 + 50923 = 51020
127 + 50893 = 51020
163 + 50857 = 51020
181 + 50839 = 51020
199 + 50821 = 51020
313 + 50707 = 51020

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51020 first appears in π at position 156,952 of the decimal expansion (the 156,952ordinal-suffix:nd 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.
