Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017786, here are decompositions:

5 + 1017781 = 1017786
37 + 1017749 = 1017786
67 + 1017719 = 1017786
73 + 1017713 = 1017786
83 + 1017703 = 1017786
103 + 1017683 = 1017786
113 + 1017673 = 1017786
137 + 1017649 = 1017786

Showing the first eight; more decompositions exist.
