Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026990, here are decompositions:

11 + 1026979 = 1026990
43 + 1026947 = 1026990
47 + 1026943 = 1026990
73 + 1026917 = 1026990
79 + 1026911 = 1026990
103 + 1026887 = 1026990
131 + 1026859 = 1026990
137 + 1026853 = 1026990

Showing the first eight; more decompositions exist.
