Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620658, here are decompositions:

19 + 8620639 = 8620658
37 + 8620621 = 8620658
229 + 8620429 = 8620658
331 + 8620327 = 8620658
439 + 8620219 = 8620658
499 + 8620159 = 8620658
547 + 8620111 = 8620658
661 + 8619997 = 8620658

Showing the first eight; more decompositions exist.
