Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040940, here are decompositions:

11 + 1040929 = 1040940
41 + 1040899 = 1040940
59 + 1040881 = 1040940
67 + 1040873 = 1040940
79 + 1040861 = 1040940
83 + 1040857 = 1040940
107 + 1040833 = 1040940
113 + 1040827 = 1040940

Showing the first eight; more decompositions exist.
