Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524498, here are decompositions:

29 + 31524469 = 31524498
79 + 31524419 = 31524498
167 + 31524331 = 31524498
197 + 31524301 = 31524498
227 + 31524271 = 31524498
241 + 31524257 = 31524498
331 + 31524167 = 31524498
337 + 31524161 = 31524498

Showing the first eight; more decompositions exist.
