Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648130, here are decompositions:

17 + 8648113 = 8648130
19 + 8648111 = 8648130
31 + 8648099 = 8648130
37 + 8648093 = 8648130
47 + 8648083 = 8648130
97 + 8648033 = 8648130
137 + 8647993 = 8648130
151 + 8647979 = 8648130

Showing the first eight; more decompositions exist.
