Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022644, here are decompositions:

5 + 1022639 = 1022644
11 + 1022633 = 1022644
53 + 1022591 = 1022644
71 + 1022573 = 1022644
113 + 1022531 = 1022644
131 + 1022513 = 1022644
137 + 1022507 = 1022644
257 + 1022387 = 1022644

Showing the first eight; more decompositions exist.
