Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12278, here are decompositions:

37 + 12241 = 12278
67 + 12211 = 12278
181 + 12097 = 12278
229 + 12049 = 12278
241 + 12037 = 12278
271 + 12007 = 12278
307 + 11971 = 12278
337 + 11941 = 12278

Showing the first eight; more decompositions exist.
