Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022240, here are decompositions:

3 + 1022237 = 1022240
31 + 1022209 = 1022240
61 + 1022179 = 1022240
73 + 1022167 = 1022240
103 + 1022137 = 1022240
127 + 1022113 = 1022240
157 + 1022083 = 1022240
181 + 1022059 = 1022240

Showing the first eight; more decompositions exist.
