Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015650, here are decompositions:

23 + 1015627 = 1015650
47 + 1015603 = 1015650
79 + 1015571 = 1015650
89 + 1015561 = 1015650
101 + 1015549 = 1015650
109 + 1015541 = 1015650
127 + 1015523 = 1015650
149 + 1015501 = 1015650

Showing the first eight; more decompositions exist.
