Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2662, here are decompositions:

3 + 2659 = 2662
5 + 2657 = 2662
29 + 2633 = 2662
41 + 2621 = 2662
53 + 2609 = 2662
71 + 2591 = 2662
83 + 2579 = 2662
113 + 2549 = 2662

Showing the first eight; more decompositions exist.
