Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524510, here are decompositions:

11 + 31524499 = 31524510
41 + 31524469 = 31524510
107 + 31524403 = 31524510
167 + 31524343 = 31524510
179 + 31524331 = 31524510
233 + 31524277 = 31524510
239 + 31524271 = 31524510
313 + 31524197 = 31524510

Showing the first eight; more decompositions exist.
