Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603664, here are decompositions:

7 + 8603657 = 8603664
53 + 8603611 = 8603664
61 + 8603603 = 8603664
67 + 8603597 = 8603664
71 + 8603593 = 8603664
73 + 8603591 = 8603664
131 + 8603533 = 8603664
193 + 8603471 = 8603664

Showing the first eight; more decompositions exist.
