Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64816, here are decompositions:

5 + 64811 = 64816
23 + 64793 = 64816
53 + 64763 = 64816
107 + 64709 = 64816
137 + 64679 = 64816
149 + 64667 = 64816
239 + 64577 = 64816
263 + 64553 = 64816

Showing the first eight; more decompositions exist.
