Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40038, here are decompositions:

7 + 40031 = 40038
29 + 40009 = 40038
59 + 39979 = 40038
67 + 39971 = 40038
101 + 39937 = 40038
109 + 39929 = 40038
137 + 39901 = 40038
151 + 39887 = 40038

Showing the first eight; more decompositions exist.
