Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048278, here are decompositions:

5 + 1048273 = 1048278
17 + 1048261 = 1048278
59 + 1048219 = 1048278
61 + 1048217 = 1048278
89 + 1048189 = 1048278
139 + 1048139 = 1048278
149 + 1048129 = 1048278
151 + 1048127 = 1048278

Showing the first eight; more decompositions exist.
