Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10040, here are decompositions:

3 + 10037 = 10040
31 + 10009 = 10040
67 + 9973 = 10040
73 + 9967 = 10040
109 + 9931 = 10040
139 + 9901 = 10040
157 + 9883 = 10040
181 + 9859 = 10040

Showing the first eight; more decompositions exist.
