Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990994, here are decompositions:

5 + 990989 = 990994
41 + 990953 = 990994
71 + 990923 = 990994
101 + 990893 = 990994
107 + 990887 = 990994
113 + 990881 = 990994
197 + 990797 = 990994
227 + 990767 = 990994

Showing the first eight; more decompositions exist.
