Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524300, here are decompositions:

7 + 31524293 = 31524300
23 + 31524277 = 31524300
29 + 31524271 = 31524300
43 + 31524257 = 31524300
103 + 31524197 = 31524300
107 + 31524193 = 31524300
139 + 31524161 = 31524300
167 + 31524133 = 31524300

Showing the first eight; more decompositions exist.
