Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022418, here are decompositions:

29 + 1022389 = 1022418
31 + 1022387 = 1022418
37 + 1022381 = 1022418
41 + 1022377 = 1022418
127 + 1022291 = 1022418
167 + 1022251 = 1022418
181 + 1022237 = 1022418
227 + 1022191 = 1022418

Showing the first eight; more decompositions exist.
