Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648470, here are decompositions:

11 + 8648459 = 8648470
23 + 8648447 = 8648470
101 + 8648369 = 8648470
137 + 8648333 = 8648470
359 + 8648111 = 8648470
491 + 8647979 = 8648470
503 + 8647967 = 8648470
521 + 8647949 = 8648470

Showing the first eight; more decompositions exist.
