Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011228, here are decompositions:

7 + 1011221 = 1011228
11 + 1011217 = 1011228
37 + 1011191 = 1011228
61 + 1011167 = 1011228
89 + 1011139 = 1011228
137 + 1011091 = 1011228
149 + 1011079 = 1011228
151 + 1011077 = 1011228

Showing the first eight; more decompositions exist.
