Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524356, here are decompositions:

13 + 31524343 = 31524356
79 + 31524277 = 31524356
163 + 31524193 = 31524356
223 + 31524133 = 31524356
307 + 31524049 = 31524356
313 + 31524043 = 31524356
439 + 31523917 = 31524356
607 + 31523749 = 31524356

Showing the first eight; more decompositions exist.
