Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615552, here are decompositions:

13 + 8615539 = 8615552
61 + 8615491 = 8615552
73 + 8615479 = 8615552
79 + 8615473 = 8615552
163 + 8615389 = 8615552
229 + 8615323 = 8615552
601 + 8614951 = 8615552
613 + 8614939 = 8615552

Showing the first eight; more decompositions exist.
