Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65066, here are decompositions:

3 + 65063 = 65066
13 + 65053 = 65066
37 + 65029 = 65066
97 + 64969 = 65066
139 + 64927 = 65066
283 + 64783 = 65066
349 + 64717 = 65066
373 + 64693 = 65066

Showing the first eight; more decompositions exist.
