Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64866, here are decompositions:

13 + 64853 = 64866
17 + 64849 = 64866
73 + 64793 = 64866
83 + 64783 = 64866
103 + 64763 = 64866
149 + 64717 = 64866
157 + 64709 = 64866
173 + 64693 = 64866

Showing the first eight; more decompositions exist.
