Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015808, here are decompositions:

61 + 1015747 = 1015808
181 + 1015627 = 1015808
307 + 1015501 = 1015808
337 + 1015471 = 1015808
349 + 1015459 = 1015808
439 + 1015369 = 1015808
499 + 1015309 = 1015808
601 + 1015207 = 1015808

Showing the first eight; more decompositions exist.
