Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524424, here are decompositions:

5 + 31524419 = 31524424
131 + 31524293 = 31524424
167 + 31524257 = 31524424
227 + 31524197 = 31524424
257 + 31524167 = 31524424
263 + 31524161 = 31524424
317 + 31524107 = 31524424
401 + 31524023 = 31524424

Showing the first eight; more decompositions exist.
