Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990154, here are decompositions:

3 + 990151 = 990154
17 + 990137 = 990154
101 + 990053 = 990154
131 + 990023 = 990154
173 + 989981 = 990154
233 + 989921 = 990154
281 + 989873 = 990154
317 + 989837 = 990154

Showing the first eight; more decompositions exist.
