Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65480, here are decompositions:

31 + 65449 = 65480
43 + 65437 = 65480
61 + 65419 = 65480
67 + 65413 = 65480
73 + 65407 = 65480
109 + 65371 = 65480
127 + 65353 = 65480
157 + 65323 = 65480

Showing the first eight; more decompositions exist.
