Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592216, here are decompositions:

3 + 31592213 = 31592216
13 + 31592203 = 31592216
43 + 31592173 = 31592216
67 + 31592149 = 31592216
163 + 31592053 = 31592216
223 + 31591993 = 31592216
307 + 31591909 = 31592216
349 + 31591867 = 31592216

Showing the first eight; more decompositions exist.
