Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524330, here are decompositions:

29 + 31524301 = 31524330
37 + 31524293 = 31524330
53 + 31524277 = 31524330
59 + 31524271 = 31524330
73 + 31524257 = 31524330
107 + 31524223 = 31524330
137 + 31524193 = 31524330
163 + 31524167 = 31524330

Showing the first eight; more decompositions exist.
