Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015646, here are decompositions:

19 + 1015627 = 1015646
43 + 1015603 = 1015646
97 + 1015549 = 1015646
139 + 1015507 = 1015646
193 + 1015453 = 1015646
223 + 1015423 = 1015646
277 + 1015369 = 1015646
283 + 1015363 = 1015646

Showing the first eight; more decompositions exist.
