Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64690, here are decompositions:

11 + 64679 = 64690
23 + 64667 = 64690
29 + 64661 = 64690
89 + 64601 = 64690
113 + 64577 = 64690
137 + 64553 = 64690
191 + 64499 = 64690
239 + 64451 = 64690

Showing the first eight; more decompositions exist.
