Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015490, here are decompositions:

19 + 1015471 = 1015490
31 + 1015459 = 1015490
37 + 1015453 = 1015490
67 + 1015423 = 1015490
127 + 1015363 = 1015490
181 + 1015309 = 1015490
283 + 1015207 = 1015490
331 + 1015159 = 1015490

Showing the first eight; more decompositions exist.
