Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40012, here are decompositions:

3 + 40009 = 40012
23 + 39989 = 40012
29 + 39983 = 40012
41 + 39971 = 40012
59 + 39953 = 40012
83 + 39929 = 40012
149 + 39863 = 40012
173 + 39839 = 40012

Showing the first eight; more decompositions exist.
