Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651616, here are decompositions:

7 + 8651609 = 8651616
13 + 8651603 = 8651616
37 + 8651579 = 8651616
67 + 8651549 = 8651616
73 + 8651543 = 8651616
79 + 8651537 = 8651616
109 + 8651507 = 8651616
157 + 8651459 = 8651616

Showing the first eight; more decompositions exist.
