Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015884, here are decompositions:

7 + 1015877 = 1015884
13 + 1015871 = 1015884
31 + 1015853 = 1015884
41 + 1015843 = 1015884
61 + 1015823 = 1015884
71 + 1015813 = 1015884
131 + 1015753 = 1015884
137 + 1015747 = 1015884

Showing the first eight; more decompositions exist.
