Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015238, here are decompositions:

31 + 1015207 = 1015238
67 + 1015171 = 1015238
79 + 1015159 = 1015238
157 + 1015081 = 1015238
181 + 1015057 = 1015238
199 + 1015039 = 1015238
229 + 1015009 = 1015238
331 + 1014907 = 1015238

Showing the first eight; more decompositions exist.
