Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71278, here are decompositions:

17 + 71261 = 71278
29 + 71249 = 71278
41 + 71237 = 71278
107 + 71171 = 71278
131 + 71147 = 71278
149 + 71129 = 71278
197 + 71081 = 71278
239 + 71039 = 71278

Showing the first eight; more decompositions exist.
