Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102512, here are decompositions:

13 + 102499 = 102512
31 + 102481 = 102512
61 + 102451 = 102512
79 + 102433 = 102512
103 + 102409 = 102512
211 + 102301 = 102512
271 + 102241 = 102512
283 + 102229 = 102512

Showing the first eight; more decompositions exist.
