Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2630, here are decompositions:

13 + 2617 = 2630
37 + 2593 = 2630
73 + 2557 = 2630
79 + 2551 = 2630
109 + 2521 = 2630
127 + 2503 = 2630
157 + 2473 = 2630
163 + 2467 = 2630

Showing the first eight; more decompositions exist.
