Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047942, here are decompositions:

13 + 1047929 = 1047942
19 + 1047923 = 1047942
59 + 1047883 = 1047942
61 + 1047881 = 1047942
83 + 1047859 = 1047942
101 + 1047841 = 1047942
109 + 1047833 = 1047942
163 + 1047779 = 1047942

Showing the first eight; more decompositions exist.
