Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015902, here are decompositions:

5 + 1015897 = 1015902
11 + 1015891 = 1015902
31 + 1015871 = 1015902
59 + 1015843 = 1015902
73 + 1015829 = 1015902
79 + 1015823 = 1015902
89 + 1015813 = 1015902
149 + 1015753 = 1015902

Showing the first eight; more decompositions exist.
