Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64210, here are decompositions:

23 + 64187 = 64210
53 + 64157 = 64210
59 + 64151 = 64210
101 + 64109 = 64210
173 + 64037 = 64210
191 + 64019 = 64210
197 + 64013 = 64210
233 + 63977 = 64210

Showing the first eight; more decompositions exist.
