Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2528, here are decompositions:

7 + 2521 = 2528
61 + 2467 = 2528
139 + 2389 = 2528
151 + 2377 = 2528
157 + 2371 = 2528
181 + 2347 = 2528
241 + 2287 = 2528
277 + 2251 = 2528

Showing the first eight; more decompositions exist.
