Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990946, here are decompositions:

23 + 990923 = 990946
29 + 990917 = 990946
53 + 990893 = 990946
59 + 990887 = 990946
137 + 990809 = 990946
149 + 990797 = 990946
179 + 990767 = 990946
227 + 990719 = 990946

Showing the first eight; more decompositions exist.
