Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2512, here are decompositions:

53 + 2459 = 2512
71 + 2441 = 2512
89 + 2423 = 2512
101 + 2411 = 2512
113 + 2399 = 2512
131 + 2381 = 2512
173 + 2339 = 2512
179 + 2333 = 2512

Showing the first eight; more decompositions exist.
