Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65518, here are decompositions:

71 + 65447 = 65518
137 + 65381 = 65518
191 + 65327 = 65518
251 + 65267 = 65518
347 + 65171 = 65518
389 + 65129 = 65518
419 + 65099 = 65518
491 + 65027 = 65518

Showing the first eight; more decompositions exist.
