Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038840, here are decompositions:

7 + 1038833 = 1038840
13 + 1038827 = 1038840
17 + 1038823 = 1038840
29 + 1038811 = 1038840
37 + 1038803 = 1038840
43 + 1038797 = 1038840
83 + 1038757 = 1038840
109 + 1038731 = 1038840

Showing the first eight; more decompositions exist.
