Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045278, here are decompositions:

5 + 1045273 = 1045278
37 + 1045241 = 1045278
41 + 1045237 = 1045278
79 + 1045199 = 1045278
127 + 1045151 = 1045278
149 + 1045129 = 1045278
167 + 1045111 = 1045278
197 + 1045081 = 1045278

Showing the first eight; more decompositions exist.
