Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12898, here are decompositions:

5 + 12893 = 12898
89 + 12809 = 12898
107 + 12791 = 12898
227 + 12671 = 12898
239 + 12659 = 12898
251 + 12647 = 12898
257 + 12641 = 12898
359 + 12539 = 12898

Showing the first eight; more decompositions exist.
