Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615616, here are decompositions:

29 + 8615587 = 8615616
73 + 8615543 = 8615616
89 + 8615527 = 8615616
103 + 8615513 = 8615616
109 + 8615507 = 8615616
137 + 8615479 = 8615616
193 + 8615423 = 8615616
227 + 8615389 = 8615616

Showing the first eight; more decompositions exist.
