Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988690, here are decompositions:

29 + 988661 = 988690
41 + 988649 = 988690
47 + 988643 = 988690
83 + 988607 = 988690
107 + 988583 = 988690
113 + 988577 = 988690
149 + 988541 = 988690
179 + 988511 = 988690

Showing the first eight; more decompositions exist.
