Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2664, here are decompositions:

5 + 2659 = 2664
7 + 2657 = 2664
17 + 2647 = 2664
31 + 2633 = 2664
43 + 2621 = 2664
47 + 2617 = 2664
71 + 2593 = 2664
73 + 2591 = 2664

Showing the first eight; more decompositions exist.
