Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90690, here are decompositions:

11 + 90679 = 90690
13 + 90677 = 90690
31 + 90659 = 90690
43 + 90647 = 90690
59 + 90631 = 90690
71 + 90619 = 90690
73 + 90617 = 90690
107 + 90583 = 90690

Showing the first eight; more decompositions exist.
