Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524032, here are decompositions:

19 + 31524013 = 31524032
79 + 31523953 = 31524032
151 + 31523881 = 31524032
181 + 31523851 = 31524032
193 + 31523839 = 31524032
229 + 31523803 = 31524032
271 + 31523761 = 31524032
283 + 31523749 = 31524032

Showing the first eight; more decompositions exist.
