Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988678, here are decompositions:

17 + 988661 = 988678
29 + 988649 = 988678
71 + 988607 = 988678
101 + 988577 = 988678
107 + 988571 = 988678
137 + 988541 = 988678
167 + 988511 = 988678
239 + 988439 = 988678

Showing the first eight; more decompositions exist.
