Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64218, here are decompositions:

29 + 64189 = 64218
31 + 64187 = 64218
47 + 64171 = 64218
61 + 64157 = 64218
67 + 64151 = 64218
109 + 64109 = 64218
127 + 64091 = 64218
137 + 64081 = 64218

Showing the first eight; more decompositions exist.
