Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015860, here are decompositions:

7 + 1015853 = 1015860
17 + 1015843 = 1015860
31 + 1015829 = 1015860
37 + 1015823 = 1015860
47 + 1015813 = 1015860
107 + 1015753 = 1015860
113 + 1015747 = 1015860
137 + 1015723 = 1015860

Showing the first eight; more decompositions exist.
