Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4656, here are decompositions:

5 + 4651 = 4656
7 + 4649 = 4656
13 + 4643 = 4656
17 + 4639 = 4656
19 + 4637 = 4656
53 + 4603 = 4656
59 + 4597 = 4656
73 + 4583 = 4656

Showing the first eight; more decompositions exist.
