Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990394, here are decompositions:

5 + 990389 = 990394
11 + 990383 = 990394
17 + 990377 = 990394
23 + 990371 = 990394
71 + 990323 = 990394
101 + 990293 = 990394
107 + 990287 = 990394
113 + 990281 = 990394

Showing the first eight; more decompositions exist.
