Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648042, here are decompositions:

79 + 8647963 = 8648042
163 + 8647879 = 8648042
223 + 8647819 = 8648042
241 + 8647801 = 8648042
283 + 8647759 = 8648042
331 + 8647711 = 8648042
463 + 8647579 = 8648042
541 + 8647501 = 8648042

Showing the first eight; more decompositions exist.
