Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015722, here are decompositions:

13 + 1015709 = 1015722
31 + 1015691 = 1015722
61 + 1015661 = 1015722
151 + 1015571 = 1015722
163 + 1015559 = 1015722
173 + 1015549 = 1015722
181 + 1015541 = 1015722
199 + 1015523 = 1015722

Showing the first eight; more decompositions exist.
