Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009448, here are decompositions:

31 + 1009417 = 1009448
61 + 1009387 = 1009448
79 + 1009369 = 1009448
127 + 1009321 = 1009448
157 + 1009291 = 1009448
211 + 1009237 = 1009448
241 + 1009207 = 1009448
457 + 1008991 = 1009448

Showing the first eight; more decompositions exist.
