Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017940, here are decompositions:

17 + 1017923 = 1017940
59 + 1017881 = 1017940
83 + 1017857 = 1017940
89 + 1017851 = 1017940
113 + 1017827 = 1017940
191 + 1017749 = 1017940
227 + 1017713 = 1017940
257 + 1017683 = 1017940

Showing the first eight; more decompositions exist.
