Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990982, here are decompositions:

29 + 990953 = 990982
59 + 990923 = 990982
89 + 990893 = 990982
101 + 990881 = 990982
131 + 990851 = 990982
173 + 990809 = 990982
263 + 990719 = 990982
383 + 990599 = 990982

Showing the first eight; more decompositions exist.
