Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2516, here are decompositions:

13 + 2503 = 2516
43 + 2473 = 2516
79 + 2437 = 2516
127 + 2389 = 2516
139 + 2377 = 2516
223 + 2293 = 2516
229 + 2287 = 2516
277 + 2239 = 2516

Showing the first eight; more decompositions exist.
