Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2536, here are decompositions:

5 + 2531 = 2536
59 + 2477 = 2536
89 + 2447 = 2536
113 + 2423 = 2536
137 + 2399 = 2536
179 + 2357 = 2536
197 + 2339 = 2536
227 + 2309 = 2536

Showing the first eight; more decompositions exist.
