Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524146, here are decompositions:

13 + 31524133 = 31524146
97 + 31524049 = 31524146
103 + 31524043 = 31524146
193 + 31523953 = 31524146
229 + 31523917 = 31524146
307 + 31523839 = 31524146
397 + 31523749 = 31524146
439 + 31523707 = 31524146

Showing the first eight; more decompositions exist.
