Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988666, here are decompositions:

5 + 988661 = 988666
17 + 988649 = 988666
23 + 988643 = 988666
59 + 988607 = 988666
83 + 988583 = 988666
89 + 988577 = 988666
227 + 988439 = 988666
257 + 988409 = 988666

Showing the first eight; more decompositions exist.
