Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015728, here are decompositions:

5 + 1015723 = 1015728
19 + 1015709 = 1015728
31 + 1015697 = 1015728
37 + 1015691 = 1015728
67 + 1015661 = 1015728
101 + 1015627 = 1015728
127 + 1015601 = 1015728
157 + 1015571 = 1015728

Showing the first eight; more decompositions exist.
