Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660992, here are decompositions:

5 + 8660987 = 8660992
23 + 8660969 = 8660992
59 + 8660933 = 8660992
71 + 8660921 = 8660992
83 + 8660909 = 8660992
101 + 8660891 = 8660992
173 + 8660819 = 8660992
239 + 8660753 = 8660992

Showing the first eight; more decompositions exist.
