Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617620, here are decompositions:

59 + 8617561 = 8617620
71 + 8617549 = 8617620
73 + 8617547 = 8617620
97 + 8617523 = 8617620
101 + 8617519 = 8617620
107 + 8617513 = 8617620
173 + 8617447 = 8617620
181 + 8617439 = 8617620

Showing the first eight; more decompositions exist.
