Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996688, here are decompositions:

41 + 996647 = 996688
59 + 996629 = 996688
71 + 996617 = 996688
89 + 996599 = 996688
137 + 996551 = 996688
149 + 996539 = 996688
227 + 996461 = 996688
257 + 996431 = 996688

Showing the first eight; more decompositions exist.
