Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63978, here are decompositions:

29 + 63949 = 63978
71 + 63907 = 63978
137 + 63841 = 63978
139 + 63839 = 63978
179 + 63799 = 63978
197 + 63781 = 63978
241 + 63737 = 63978
251 + 63727 = 63978

Showing the first eight; more decompositions exist.
