Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022078, here are decompositions:

7 + 1022071 = 1022078
19 + 1022059 = 1022078
61 + 1022017 = 1022078
67 + 1022011 = 1022078
181 + 1021897 = 1022078
199 + 1021879 = 1022078
229 + 1021849 = 1022078
241 + 1021837 = 1022078

Showing the first eight; more decompositions exist.
