Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64280, here are decompositions:

43 + 64237 = 64280
109 + 64171 = 64280
127 + 64153 = 64280
157 + 64123 = 64280
199 + 64081 = 64280
283 + 63997 = 64280
331 + 63949 = 64280
367 + 63913 = 64280

Showing the first eight; more decompositions exist.
