Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648146, here are decompositions:

47 + 8648099 = 8648146
53 + 8648093 = 8648146
113 + 8648033 = 8648146
149 + 8647997 = 8648146
167 + 8647979 = 8648146
179 + 8647967 = 8648146
197 + 8647949 = 8648146
233 + 8647913 = 8648146

Showing the first eight; more decompositions exist.
