Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615620, here are decompositions:

29 + 8615591 = 8615620
53 + 8615567 = 8615620
107 + 8615513 = 8615620
113 + 8615507 = 8615620
149 + 8615471 = 8615620
197 + 8615423 = 8615620
347 + 8615273 = 8615620
353 + 8615267 = 8615620

Showing the first eight; more decompositions exist.
