Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648372, here are decompositions:

3 + 8648369 = 8648372
151 + 8648221 = 8648372
181 + 8648191 = 8648372
193 + 8648179 = 8648372
223 + 8648149 = 8648372
241 + 8648131 = 8648372
379 + 8647993 = 8648372
409 + 8647963 = 8648372

Showing the first eight; more decompositions exist.
