Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648144, here are decompositions:

13 + 8648131 = 8648144
31 + 8648113 = 8648144
61 + 8648083 = 8648144
151 + 8647993 = 8648144
181 + 8647963 = 8648144
433 + 8647711 = 8648144
487 + 8647657 = 8648144
577 + 8647567 = 8648144

Showing the first eight; more decompositions exist.
