Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655744, here are decompositions:

5 + 8655739 = 8655744
11 + 8655733 = 8655744
23 + 8655721 = 8655744
37 + 8655707 = 8655744
43 + 8655701 = 8655744
67 + 8655677 = 8655744
73 + 8655671 = 8655744
103 + 8655641 = 8655744

Showing the first eight; more decompositions exist.
