Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988668, here are decompositions:

7 + 988661 = 988668
17 + 988651 = 988668
19 + 988649 = 988668
61 + 988607 = 988668
89 + 988579 = 988668
97 + 988571 = 988668
127 + 988541 = 988668
157 + 988511 = 988668

Showing the first eight; more decompositions exist.
