Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022480, here are decompositions:

13 + 1022467 = 1022480
31 + 1022449 = 1022480
37 + 1022443 = 1022480
97 + 1022383 = 1022480
103 + 1022377 = 1022480
139 + 1022341 = 1022480
229 + 1022251 = 1022480
271 + 1022209 = 1022480

Showing the first eight; more decompositions exist.
