Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65380, here are decompositions:

23 + 65357 = 65380
53 + 65327 = 65380
71 + 65309 = 65380
113 + 65267 = 65380
167 + 65213 = 65380
197 + 65183 = 65380
233 + 65147 = 65380
239 + 65141 = 65380

Showing the first eight; more decompositions exist.
