Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015998, here are decompositions:

7 + 1015991 = 1015998
17 + 1015981 = 1015998
31 + 1015967 = 1015998
79 + 1015919 = 1015998
101 + 1015897 = 1015998
107 + 1015891 = 1015998
127 + 1015871 = 1015998
229 + 1015769 = 1015998

Showing the first eight; more decompositions exist.
