Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641616, here are decompositions:

3 + 8641613 = 8641616
13 + 8641603 = 8641616
73 + 8641543 = 8641616
97 + 8641519 = 8641616
103 + 8641513 = 8641616
163 + 8641453 = 8641616
307 + 8641309 = 8641616
367 + 8641249 = 8641616

Showing the first eight; more decompositions exist.
