Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40010, here are decompositions:

31 + 39979 = 40010
73 + 39937 = 40010
109 + 39901 = 40010
127 + 39883 = 40010
163 + 39847 = 40010
181 + 39829 = 40010
211 + 39799 = 40010
241 + 39769 = 40010

Showing the first eight; more decompositions exist.
