Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990774, here are decompositions:

7 + 990767 = 990774
13 + 990761 = 990774
41 + 990733 = 990774
67 + 990707 = 990774
101 + 990673 = 990774
131 + 990643 = 990774
137 + 990637 = 990774
181 + 990593 = 990774

Showing the first eight; more decompositions exist.
