Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40112, here are decompositions:

13 + 40099 = 40112
19 + 40093 = 40112
73 + 40039 = 40112
103 + 40009 = 40112
211 + 39901 = 40112
229 + 39883 = 40112
271 + 39841 = 40112
283 + 39829 = 40112

Showing the first eight; more decompositions exist.
