Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988660, here are decompositions:

11 + 988649 = 988660
17 + 988643 = 988660
53 + 988607 = 988660
83 + 988577 = 988660
89 + 988571 = 988660
149 + 988511 = 988660
251 + 988409 = 988660
293 + 988367 = 988660

Showing the first eight; more decompositions exist.
