Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990382, here are decompositions:

5 + 990377 = 990382
11 + 990371 = 990382
23 + 990359 = 990382
53 + 990329 = 990382
59 + 990323 = 990382
89 + 990293 = 990382
101 + 990281 = 990382
359 + 990023 = 990382

Showing the first eight; more decompositions exist.
