Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524342, here are decompositions:

11 + 31524331 = 31524342
41 + 31524301 = 31524342
71 + 31524271 = 31524342
149 + 31524193 = 31524342
181 + 31524161 = 31524342
251 + 31524091 = 31524342
293 + 31524049 = 31524342
331 + 31524011 = 31524342

Showing the first eight; more decompositions exist.
