Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2902, here are decompositions:

5 + 2897 = 2902
23 + 2879 = 2902
41 + 2861 = 2902
59 + 2843 = 2902
83 + 2819 = 2902
101 + 2801 = 2902
113 + 2789 = 2902
149 + 2753 = 2902

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2902 first appears in π at position 713 of the decimal expansion (the 713ordinal-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.
