Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023228, here are decompositions:

7 + 1023221 = 1023228
29 + 1023199 = 1023228
61 + 1023167 = 1023228
127 + 1023101 = 1023228
149 + 1023079 = 1023228
181 + 1023047 = 1023228
191 + 1023037 = 1023228
251 + 1022977 = 1023228

Showing the first eight; more decompositions exist.
