Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990248, here are decompositions:

37 + 990211 = 990248
67 + 990181 = 990248
79 + 990169 = 990248
97 + 990151 = 990248
211 + 990037 = 990248
271 + 989977 = 990248
277 + 989971 = 990248
331 + 989917 = 990248

Showing the first eight; more decompositions exist.
