Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524452, here are decompositions:

109 + 31524343 = 31524452
151 + 31524301 = 31524452
181 + 31524271 = 31524452
229 + 31524223 = 31524452
409 + 31524043 = 31524452
439 + 31524013 = 31524452
499 + 31523953 = 31524452
571 + 31523881 = 31524452

Showing the first eight; more decompositions exist.
