Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015778, here are decompositions:

31 + 1015747 = 1015778
151 + 1015627 = 1015778
229 + 1015549 = 1015778
271 + 1015507 = 1015778
277 + 1015501 = 1015778
307 + 1015471 = 1015778
409 + 1015369 = 1015778
571 + 1015207 = 1015778

Showing the first eight; more decompositions exist.
