Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651078, here are decompositions:

31 + 8651047 = 8651078
61 + 8651017 = 8651078
97 + 8650981 = 8651078
151 + 8650927 = 8651078
181 + 8650897 = 8651078
199 + 8650879 = 8651078
229 + 8650849 = 8651078
409 + 8650669 = 8651078

Showing the first eight; more decompositions exist.
