Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990664, here are decompositions:

71 + 990593 = 990664
167 + 990497 = 990664
281 + 990383 = 990664
293 + 990371 = 990664
383 + 990281 = 990664
641 + 990023 = 990664
683 + 989981 = 990664
743 + 989921 = 990664

Showing the first eight; more decompositions exist.
