Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047782, here are decompositions:

3 + 1047779 = 1047782
19 + 1047763 = 1047782
31 + 1047751 = 1047782
61 + 1047721 = 1047782
79 + 1047703 = 1047782
193 + 1047589 = 1047782
223 + 1047559 = 1047782
271 + 1047511 = 1047782

Showing the first eight; more decompositions exist.
