Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64988, here are decompositions:

19 + 64969 = 64988
37 + 64951 = 64988
61 + 64927 = 64988
67 + 64921 = 64988
97 + 64891 = 64988
109 + 64879 = 64988
139 + 64849 = 64988
241 + 64747 = 64988

Showing the first eight; more decompositions exist.
