Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988672, here are decompositions:

11 + 988661 = 988672
23 + 988649 = 988672
29 + 988643 = 988672
89 + 988583 = 988672
101 + 988571 = 988672
131 + 988541 = 988672
233 + 988439 = 988672
263 + 988409 = 988672

Showing the first eight; more decompositions exist.
