Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019940, here are decompositions:

13 + 1019927 = 1019940
37 + 1019903 = 1019940
41 + 1019899 = 1019940
67 + 1019873 = 1019940
79 + 1019861 = 1019940
83 + 1019857 = 1019940
101 + 1019839 = 1019940
113 + 1019827 = 1019940

Showing the first eight; more decompositions exist.
