Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990746, here are decompositions:

13 + 990733 = 990746
73 + 990673 = 990746
103 + 990643 = 990746
109 + 990637 = 990746
157 + 990589 = 990746
199 + 990547 = 990746
223 + 990523 = 990746
277 + 990469 = 990746

Showing the first eight; more decompositions exist.
