Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620612, here are decompositions:

23 + 8620589 = 8620612
41 + 8620571 = 8620612
59 + 8620553 = 8620612
83 + 8620529 = 8620612
113 + 8620499 = 8620612
251 + 8620361 = 8620612
263 + 8620349 = 8620612
353 + 8620259 = 8620612

Showing the first eight; more decompositions exist.
