Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990070, here are decompositions:

17 + 990053 = 990070
47 + 990023 = 990070
71 + 989999 = 990070
89 + 989981 = 990070
131 + 989939 = 990070
149 + 989921 = 990070
197 + 989873 = 990070
233 + 989837 = 990070

Showing the first eight; more decompositions exist.
