Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026220, here are decompositions:

3 + 1026217 = 1026220
23 + 1026197 = 1026220
53 + 1026167 = 1026220
101 + 1026119 = 1026220
179 + 1026041 = 1026220
191 + 1026029 = 1026220
263 + 1025957 = 1026220
281 + 1025939 = 1026220

Showing the first eight; more decompositions exist.
