Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4650, here are decompositions:

7 + 4643 = 4650
11 + 4639 = 4650
13 + 4637 = 4650
29 + 4621 = 4650
47 + 4603 = 4650
53 + 4597 = 4650
59 + 4591 = 4650
67 + 4583 = 4650

Showing the first eight; more decompositions exist.
