Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64278, here are decompositions:

7 + 64271 = 64278
41 + 64237 = 64278
47 + 64231 = 64278
61 + 64217 = 64278
89 + 64189 = 64278
107 + 64171 = 64278
127 + 64151 = 64278
197 + 64081 = 64278

Showing the first eight; more decompositions exist.
