Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021418, here are decompositions:

31 + 1021387 = 1021418
37 + 1021381 = 1021418
127 + 1021291 = 1021418
157 + 1021261 = 1021418
331 + 1021087 = 1021418
337 + 1021081 = 1021418
421 + 1020997 = 1021418
439 + 1020979 = 1021418

Showing the first eight; more decompositions exist.
