Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656998, here are decompositions:

19 + 8656979 = 8656998
59 + 8656939 = 8656998
79 + 8656919 = 8656998
101 + 8656897 = 8656998
107 + 8656891 = 8656998
127 + 8656871 = 8656998
149 + 8656849 = 8656998
151 + 8656847 = 8656998

Showing the first eight; more decompositions exist.
