Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990216, here are decompositions:

5 + 990211 = 990216
37 + 990179 = 990216
47 + 990169 = 990216
53 + 990163 = 990216
79 + 990137 = 990216
163 + 990053 = 990216
173 + 990043 = 990216
179 + 990037 = 990216

Showing the first eight; more decompositions exist.
