Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022288, here are decompositions:

37 + 1022251 = 1022288
79 + 1022209 = 1022288
97 + 1022191 = 1022288
109 + 1022179 = 1022288
151 + 1022137 = 1022288
229 + 1022059 = 1022288
271 + 1022017 = 1022288
277 + 1022011 = 1022288

Showing the first eight; more decompositions exist.
