Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2620, here are decompositions:

3 + 2617 = 2620
11 + 2609 = 2620
29 + 2591 = 2620
41 + 2579 = 2620
71 + 2549 = 2620
89 + 2531 = 2620
173 + 2447 = 2620
179 + 2441 = 2620

Showing the first eight; more decompositions exist.
