Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988686, here are decompositions:

5 + 988681 = 988686
37 + 988649 = 988686
43 + 988643 = 988686
79 + 988607 = 988686
103 + 988583 = 988686
107 + 988579 = 988686
109 + 988577 = 988686
137 + 988549 = 988686

Showing the first eight; more decompositions exist.
