Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43218, here are decompositions:

11 + 43207 = 43218
17 + 43201 = 43218
29 + 43189 = 43218
41 + 43177 = 43218
59 + 43159 = 43218
67 + 43151 = 43218
101 + 43117 = 43218
151 + 43067 = 43218

Showing the first eight; more decompositions exist.
