Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524226, here are decompositions:

3 + 31524223 = 31524226
29 + 31524197 = 31524226
59 + 31524167 = 31524226
179 + 31524047 = 31524226
557 + 31523669 = 31524226
593 + 31523633 = 31524226
647 + 31523579 = 31524226
827 + 31523399 = 31524226

Showing the first eight; more decompositions exist.
