Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2650, here are decompositions:

3 + 2647 = 2650
17 + 2633 = 2650
29 + 2621 = 2650
41 + 2609 = 2650
59 + 2591 = 2650
71 + 2579 = 2650
101 + 2549 = 2650
107 + 2543 = 2650

Showing the first eight; more decompositions exist.
