Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4626, here are decompositions:

5 + 4621 = 4626
23 + 4603 = 4626
29 + 4597 = 4626
43 + 4583 = 4626
59 + 4567 = 4626
79 + 4547 = 4626
103 + 4523 = 4626
107 + 4519 = 4626

Showing the first eight; more decompositions exist.
