Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015850, here are decompositions:

7 + 1015843 = 1015850
37 + 1015813 = 1015850
97 + 1015753 = 1015850
103 + 1015747 = 1015850
127 + 1015723 = 1015850
223 + 1015627 = 1015850
349 + 1015501 = 1015850
379 + 1015471 = 1015850

Showing the first eight; more decompositions exist.
