Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047990, here are decompositions:

11 + 1047979 = 1047990
19 + 1047971 = 1047990
29 + 1047961 = 1047990
61 + 1047929 = 1047990
67 + 1047923 = 1047990
103 + 1047887 = 1047990
107 + 1047883 = 1047990
109 + 1047881 = 1047990

Showing the first eight; more decompositions exist.
