Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622448, here are decompositions:

89 + 8622359 = 8622448
239 + 8622209 = 8622448
257 + 8622191 = 8622448
311 + 8622137 = 8622448
431 + 8622017 = 8622448
509 + 8621939 = 8622448
521 + 8621927 = 8622448
587 + 8621861 = 8622448

Showing the first eight; more decompositions exist.
