Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524374, here are decompositions:

31 + 31524343 = 31524374
43 + 31524331 = 31524374
73 + 31524301 = 31524374
97 + 31524277 = 31524374
103 + 31524271 = 31524374
151 + 31524223 = 31524374
181 + 31524193 = 31524374
241 + 31524133 = 31524374

Showing the first eight; more decompositions exist.
