Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007940, here are decompositions:

7 + 1007933 = 1007940
19 + 1007921 = 1007940
53 + 1007887 = 1007940
67 + 1007873 = 1007940
79 + 1007861 = 1007940
83 + 1007857 = 1007940
113 + 1007827 = 1007940
127 + 1007813 = 1007940

Showing the first eight; more decompositions exist.
