Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43278, here are decompositions:

7 + 43271 = 43278
17 + 43261 = 43278
41 + 43237 = 43278
71 + 43207 = 43278
89 + 43189 = 43278
101 + 43177 = 43278
127 + 43151 = 43278
211 + 43067 = 43278

Showing the first eight; more decompositions exist.
