Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015356, here are decompositions:

7 + 1015349 = 1015356
47 + 1015309 = 1015356
79 + 1015277 = 1015356
149 + 1015207 = 1015356
157 + 1015199 = 1015356
193 + 1015163 = 1015356
197 + 1015159 = 1015356
229 + 1015127 = 1015356

Showing the first eight; more decompositions exist.
