Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988656, here are decompositions:

5 + 988651 = 988656
7 + 988649 = 988656
13 + 988643 = 988656
73 + 988583 = 988656
79 + 988577 = 988656
107 + 988549 = 988656
167 + 988489 = 988656
173 + 988483 = 988656

Showing the first eight; more decompositions exist.
