Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2618, here are decompositions:

61 + 2557 = 2618
67 + 2551 = 2618
79 + 2539 = 2618
97 + 2521 = 2618
151 + 2467 = 2618
181 + 2437 = 2618
229 + 2389 = 2618
241 + 2377 = 2618

Showing the first eight; more decompositions exist.
