Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524402, here are decompositions:

59 + 31524343 = 31524402
71 + 31524331 = 31524402
101 + 31524301 = 31524402
109 + 31524293 = 31524402
131 + 31524271 = 31524402
179 + 31524223 = 31524402
241 + 31524161 = 31524402
269 + 31524133 = 31524402

Showing the first eight; more decompositions exist.
