Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620574, here are decompositions:

3 + 8620571 = 8620574
7 + 8620567 = 8620574
31 + 8620543 = 8620574
181 + 8620393 = 8620574
307 + 8620267 = 8620574
433 + 8620141 = 8620574
463 + 8620111 = 8620574
577 + 8619997 = 8620574

Showing the first eight; more decompositions exist.
