Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015390, here are decompositions:

23 + 1015367 = 1015390
29 + 1015361 = 1015390
41 + 1015349 = 1015390
113 + 1015277 = 1015390
191 + 1015199 = 1015390
227 + 1015163 = 1015390
251 + 1015139 = 1015390
263 + 1015127 = 1015390

Showing the first eight; more decompositions exist.
