Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557352, here are decompositions:

23 + 31557329 = 31557352
59 + 31557293 = 31557352
149 + 31557203 = 31557352
173 + 31557179 = 31557352
191 + 31557161 = 31557352
443 + 31556909 = 31557352
863 + 31556489 = 31557352
929 + 31556423 = 31557352

Showing the first eight; more decompositions exist.
