Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2634, here are decompositions:

13 + 2621 = 2634
17 + 2617 = 2634
41 + 2593 = 2634
43 + 2591 = 2634
83 + 2551 = 2634
103 + 2531 = 2634
113 + 2521 = 2634
131 + 2503 = 2634

Showing the first eight; more decompositions exist.
