Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019220, here are decompositions:

11 + 1019209 = 1019220
23 + 1019197 = 1019220
43 + 1019177 = 1019220
47 + 1019173 = 1019220
101 + 1019119 = 1019220
127 + 1019093 = 1019220
149 + 1019071 = 1019220
151 + 1019069 = 1019220

Showing the first eight; more decompositions exist.
