Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524314, here are decompositions:

13 + 31524301 = 31524314
37 + 31524277 = 31524314
43 + 31524271 = 31524314
181 + 31524133 = 31524314
223 + 31524091 = 31524314
271 + 31524043 = 31524314
373 + 31523941 = 31524314
397 + 31523917 = 31524314

Showing the first eight; more decompositions exist.
