Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047940, here are decompositions:

11 + 1047929 = 1047940
17 + 1047923 = 1047940
53 + 1047887 = 1047940
59 + 1047881 = 1047940
107 + 1047833 = 1047940
167 + 1047773 = 1047940
227 + 1047713 = 1047940
239 + 1047701 = 1047940

Showing the first eight; more decompositions exist.
