Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620618, here are decompositions:

29 + 8620589 = 8620618
47 + 8620571 = 8620618
89 + 8620529 = 8620618
257 + 8620361 = 8620618
269 + 8620349 = 8620618
311 + 8620307 = 8620618
359 + 8620259 = 8620618
401 + 8620217 = 8620618

Showing the first eight; more decompositions exist.
