Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63740, here are decompositions:

3 + 63737 = 63740
13 + 63727 = 63740
31 + 63709 = 63740
37 + 63703 = 63740
43 + 63697 = 63740
73 + 63667 = 63740
139 + 63601 = 63740
151 + 63589 = 63740

Showing the first eight; more decompositions exist.
