Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022748, here are decompositions:

19 + 1022729 = 1022748
29 + 1022719 = 1022748
47 + 1022701 = 1022748
59 + 1022689 = 1022748
71 + 1022677 = 1022748
109 + 1022639 = 1022748
137 + 1022611 = 1022748
157 + 1022591 = 1022748

Showing the first eight; more decompositions exist.
