Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015984, here are decompositions:

3 + 1015981 = 1015984
17 + 1015967 = 1015984
71 + 1015913 = 1015984
107 + 1015877 = 1015984
113 + 1015871 = 1015984
131 + 1015853 = 1015984
257 + 1015727 = 1015984
293 + 1015691 = 1015984

Showing the first eight; more decompositions exist.
