Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038940, here are decompositions:

3 + 1038937 = 1038940
59 + 1038881 = 1038940
107 + 1038833 = 1038940
113 + 1038827 = 1038940
137 + 1038803 = 1038940
233 + 1038707 = 1038940
251 + 1038689 = 1038940
269 + 1038671 = 1038940

Showing the first eight; more decompositions exist.
