Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717992, here are decompositions:

5 + 8717987 = 8717992
11 + 8717981 = 8717992
29 + 8717963 = 8717992
53 + 8717939 = 8717992
83 + 8717909 = 8717992
131 + 8717861 = 8717992
149 + 8717843 = 8717992
251 + 8717741 = 8717992

Showing the first eight; more decompositions exist.
