Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039940, here are decompositions:

19 + 1039921 = 1039940
43 + 1039897 = 1039940
103 + 1039837 = 1039940
151 + 1039789 = 1039940
283 + 1039657 = 1039940
337 + 1039603 = 1039940
397 + 1039543 = 1039940
463 + 1039477 = 1039940

Showing the first eight; more decompositions exist.
