Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990338, here are decompositions:

7 + 990331 = 990338
31 + 990307 = 990338
61 + 990277 = 990338
79 + 990259 = 990338
127 + 990211 = 990338
157 + 990181 = 990338
337 + 990001 = 990338
367 + 989971 = 990338

Showing the first eight; more decompositions exist.
