Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008990, here are decompositions:

7 + 1008983 = 1008990
11 + 1008979 = 1008990
43 + 1008947 = 1008990
53 + 1008937 = 1008990
67 + 1008923 = 1008990
79 + 1008911 = 1008990
89 + 1008901 = 1008990
127 + 1008863 = 1008990

Showing the first eight; more decompositions exist.
