Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40740, here are decompositions:

31 + 40709 = 40740
41 + 40699 = 40740
43 + 40697 = 40740
47 + 40693 = 40740
101 + 40639 = 40740
103 + 40637 = 40740
113 + 40627 = 40740
131 + 40609 = 40740

Showing the first eight; more decompositions exist.
