Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656992, here are decompositions:

13 + 8656979 = 8656992
53 + 8656939 = 8656992
59 + 8656933 = 8656992
73 + 8656919 = 8656992
89 + 8656903 = 8656992
101 + 8656891 = 8656992
163 + 8656829 = 8656992
191 + 8656801 = 8656992

Showing the first eight; more decompositions exist.
