Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990750, here are decompositions:

17 + 990733 = 990750
31 + 990719 = 990750
43 + 990707 = 990750
107 + 990643 = 990750
113 + 990637 = 990750
151 + 990599 = 990750
157 + 990593 = 990750
191 + 990559 = 990750

Showing the first eight; more decompositions exist.
