Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65446, here are decompositions:

23 + 65423 = 65446
53 + 65393 = 65446
89 + 65357 = 65446
137 + 65309 = 65446
179 + 65267 = 65446
233 + 65213 = 65446
263 + 65183 = 65446
317 + 65129 = 65446

Showing the first eight; more decompositions exist.
