Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015230, here are decompositions:

23 + 1015207 = 1015230
31 + 1015199 = 1015230
59 + 1015171 = 1015230
67 + 1015163 = 1015230
71 + 1015159 = 1015230
103 + 1015127 = 1015230
107 + 1015123 = 1015230
137 + 1015093 = 1015230

Showing the first eight; more decompositions exist.
