Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41278, here are decompositions:

47 + 41231 = 41278
89 + 41189 = 41278
101 + 41177 = 41278
137 + 41141 = 41278
197 + 41081 = 41278
227 + 41051 = 41278
239 + 41039 = 41278
317 + 40961 = 41278

Showing the first eight; more decompositions exist.
