Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020648, here are decompositions:

17 + 1020631 = 1020648
29 + 1020619 = 1020648
59 + 1020589 = 1020648
107 + 1020541 = 1020648
131 + 1020517 = 1020648
157 + 1020491 = 1020648
191 + 1020457 = 1020648
197 + 1020451 = 1020648

Showing the first eight; more decompositions exist.
