Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65218, here are decompositions:

5 + 65213 = 65218
47 + 65171 = 65218
71 + 65147 = 65218
89 + 65129 = 65218
107 + 65111 = 65218
191 + 65027 = 65218
281 + 64937 = 65218
317 + 64901 = 65218

Showing the first eight; more decompositions exist.
