Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050, here are decompositions:

11 + 1039 = 1050
17 + 1033 = 1050
19 + 1031 = 1050
29 + 1021 = 1050
31 + 1019 = 1050
37 + 1013 = 1050
41 + 1009 = 1050
53 + 997 = 1050

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1050 first appears in π at position 681 of the decimal expansion (the 681ordinal-suffix:st 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.
