Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019216, here are decompositions:

7 + 1019209 = 1019216
19 + 1019197 = 1019216
43 + 1019173 = 1019216
97 + 1019119 = 1019216
139 + 1019077 = 1019216
157 + 1019059 = 1019216
193 + 1019023 = 1019216
223 + 1018993 = 1019216

Showing the first eight; more decompositions exist.
