Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647992, here are decompositions:

13 + 8647979 = 8647992
29 + 8647963 = 8647992
43 + 8647949 = 8647992
79 + 8647913 = 8647992
103 + 8647889 = 8647992
113 + 8647879 = 8647992
173 + 8647819 = 8647992
191 + 8647801 = 8647992

Showing the first eight; more decompositions exist.
