Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990654, here are decompositions:

11 + 990643 = 990654
17 + 990637 = 990654
23 + 990631 = 990654
61 + 990593 = 990654
107 + 990547 = 990654
131 + 990523 = 990654
151 + 990503 = 990654
157 + 990497 = 990654

Showing the first eight; more decompositions exist.
