Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64220, here are decompositions:

3 + 64217 = 64220
31 + 64189 = 64220
67 + 64153 = 64220
97 + 64123 = 64220
139 + 64081 = 64220
157 + 64063 = 64220
223 + 63997 = 64220
271 + 63949 = 64220

Showing the first eight; more decompositions exist.
