Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65418, here are decompositions:

5 + 65413 = 65418
11 + 65407 = 65418
37 + 65381 = 65418
47 + 65371 = 65418
61 + 65357 = 65418
109 + 65309 = 65418
131 + 65287 = 65418
149 + 65269 = 65418

Showing the first eight; more decompositions exist.
