Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63980, here are decompositions:

3 + 63977 = 63980
31 + 63949 = 63980
67 + 63913 = 63980
73 + 63907 = 63980
79 + 63901 = 63980
127 + 63853 = 63980
139 + 63841 = 63980
157 + 63823 = 63980

Showing the first eight; more decompositions exist.
