Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990568, here are decompositions:

71 + 990497 = 990568
179 + 990389 = 990568
191 + 990377 = 990568
197 + 990371 = 990568
239 + 990329 = 990568
281 + 990287 = 990568
389 + 990179 = 990568
431 + 990137 = 990568

Showing the first eight; more decompositions exist.
