Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64998, here are decompositions:

29 + 64969 = 64998
47 + 64951 = 64998
61 + 64937 = 64998
71 + 64927 = 64998
79 + 64919 = 64998
97 + 64901 = 64998
107 + 64891 = 64998
127 + 64871 = 64998

Showing the first eight; more decompositions exist.
