Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990546, here are decompositions:

17 + 990529 = 990546
23 + 990523 = 990546
43 + 990503 = 990546
59 + 990487 = 990546
83 + 990463 = 990546
149 + 990397 = 990546
157 + 990389 = 990546
163 + 990383 = 990546

Showing the first eight; more decompositions exist.
