Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983990, here are decompositions:

3 + 983987 = 983990
61 + 983929 = 983990
67 + 983923 = 983990
79 + 983911 = 983990
109 + 983881 = 983990
127 + 983863 = 983990
181 + 983809 = 983990
199 + 983791 = 983990

Showing the first eight; more decompositions exist.
