Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015158, here are decompositions:

19 + 1015139 = 1015158
31 + 1015127 = 1015158
61 + 1015097 = 1015158
97 + 1015061 = 1015158
101 + 1015057 = 1015158
107 + 1015051 = 1015158
149 + 1015009 = 1015158
251 + 1014907 = 1015158

Showing the first eight; more decompositions exist.
