Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008228, here are decompositions:

5 + 1008223 = 1008228
19 + 1008209 = 1008228
29 + 1008199 = 1008228
41 + 1008187 = 1008228
47 + 1008181 = 1008228
71 + 1008157 = 1008228
97 + 1008131 = 1008228
127 + 1008101 = 1008228

Showing the first eight; more decompositions exist.
