Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019228, here are decompositions:

19 + 1019209 = 1019228
31 + 1019197 = 1019228
109 + 1019119 = 1019228
151 + 1019077 = 1019228
157 + 1019071 = 1019228
229 + 1018999 = 1019228
241 + 1018987 = 1019228
271 + 1018957 = 1019228

Showing the first eight; more decompositions exist.
