Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65290, here are decompositions:

3 + 65287 = 65290
23 + 65267 = 65290
107 + 65183 = 65290
149 + 65141 = 65290
167 + 65123 = 65290
179 + 65111 = 65290
191 + 65099 = 65290
227 + 65063 = 65290

Showing the first eight; more decompositions exist.
