Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572334, here are decompositions:

11 + 31572323 = 31572334
71 + 31572263 = 31572334
107 + 31572227 = 31572334
113 + 31572221 = 31572334
173 + 31572161 = 31572334
191 + 31572143 = 31572334
251 + 31572083 = 31572334
293 + 31572041 = 31572334

Showing the first eight; more decompositions exist.
