Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64986, here are decompositions:

17 + 64969 = 64986
59 + 64927 = 64986
67 + 64919 = 64986
107 + 64879 = 64986
109 + 64877 = 64986
137 + 64849 = 64986
193 + 64793 = 64986
223 + 64763 = 64986

Showing the first eight; more decompositions exist.
