Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12478, here are decompositions:

5 + 12473 = 12478
41 + 12437 = 12478
101 + 12377 = 12478
131 + 12347 = 12478
149 + 12329 = 12478
197 + 12281 = 12478
227 + 12251 = 12478
239 + 12239 = 12478

Showing the first eight; more decompositions exist.
