Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022650, here are decompositions:

11 + 1022639 = 1022650
17 + 1022633 = 1022650
59 + 1022591 = 1022650
131 + 1022519 = 1022650
137 + 1022513 = 1022650
149 + 1022501 = 1022650
263 + 1022387 = 1022650
269 + 1022381 = 1022650

Showing the first eight; more decompositions exist.
