Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64040, here are decompositions:

3 + 64037 = 64040
7 + 64033 = 64040
43 + 63997 = 64040
127 + 63913 = 64040
139 + 63901 = 64040
199 + 63841 = 64040
241 + 63799 = 64040
313 + 63727 = 64040

Showing the first eight; more decompositions exist.
