Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65006, here are decompositions:

3 + 65003 = 65006
37 + 64969 = 65006
79 + 64927 = 65006
127 + 64879 = 65006
157 + 64849 = 65006
223 + 64783 = 65006
313 + 64693 = 65006
373 + 64633 = 65006

Showing the first eight; more decompositions exist.
