Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990298, here are decompositions:

5 + 990293 = 990298
11 + 990287 = 990298
17 + 990281 = 990298
59 + 990239 = 990298
317 + 989981 = 990298
347 + 989951 = 990298
359 + 989939 = 990298
389 + 989909 = 990298

Showing the first eight; more decompositions exist.
