Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015290, here are decompositions:

13 + 1015277 = 1015290
83 + 1015207 = 1015290
127 + 1015163 = 1015290
131 + 1015159 = 1015290
151 + 1015139 = 1015290
163 + 1015127 = 1015290
167 + 1015123 = 1015290
193 + 1015097 = 1015290

Showing the first eight; more decompositions exist.
