Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2616, here are decompositions:

7 + 2609 = 2616
23 + 2593 = 2616
37 + 2579 = 2616
59 + 2557 = 2616
67 + 2549 = 2616
73 + 2543 = 2616
113 + 2503 = 2616
139 + 2477 = 2616

Showing the first eight; more decompositions exist.
