Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022544, here are decompositions:

13 + 1022531 = 1022544
31 + 1022513 = 1022544
37 + 1022507 = 1022544
41 + 1022503 = 1022544
43 + 1022501 = 1022544
53 + 1022491 = 1022544
101 + 1022443 = 1022544
157 + 1022387 = 1022544

Showing the first eight; more decompositions exist.
