Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009278, here are decompositions:

19 + 1009259 = 1009278
31 + 1009247 = 1009278
41 + 1009237 = 1009278
71 + 1009207 = 1009278
79 + 1009199 = 1009278
89 + 1009189 = 1009278
139 + 1009139 = 1009278
157 + 1009121 = 1009278

Showing the first eight; more decompositions exist.
