Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2670, here are decompositions:

7 + 2663 = 2670
11 + 2659 = 2670
13 + 2657 = 2670
23 + 2647 = 2670
37 + 2633 = 2670
53 + 2617 = 2670
61 + 2609 = 2670
79 + 2591 = 2670

Showing the first eight; more decompositions exist.
