Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990356, here are decompositions:

7 + 990349 = 990356
43 + 990313 = 990356
67 + 990289 = 990356
79 + 990277 = 990356
97 + 990259 = 990356
193 + 990163 = 990356
313 + 990043 = 990356
379 + 989977 = 990356

Showing the first eight; more decompositions exist.
