Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990286, here are decompositions:

5 + 990281 = 990286
47 + 990239 = 990286
107 + 990179 = 990286
149 + 990137 = 990286
233 + 990053 = 990286
263 + 990023 = 990286
347 + 989939 = 990286
449 + 989837 = 990286

Showing the first eight; more decompositions exist.
