Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12748, here are decompositions:

5 + 12743 = 12748
59 + 12689 = 12748
89 + 12659 = 12748
101 + 12647 = 12748
107 + 12641 = 12748
137 + 12611 = 12748
179 + 12569 = 12748
251 + 12497 = 12748

Showing the first eight; more decompositions exist.
