Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025228, here are decompositions:

19 + 1025209 = 1025228
31 + 1025197 = 1025228
67 + 1025161 = 1025228
79 + 1025149 = 1025228
109 + 1025119 = 1025228
181 + 1025047 = 1025228
199 + 1025029 = 1025228
241 + 1024987 = 1025228

Showing the first eight; more decompositions exist.
