Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599152, here are decompositions:

163 + 31598989 = 31599152
199 + 31598953 = 31599152
229 + 31598923 = 31599152
241 + 31598911 = 31599152
313 + 31598839 = 31599152
373 + 31598779 = 31599152
631 + 31598521 = 31599152
733 + 31598419 = 31599152

Showing the first eight; more decompositions exist.
