Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524020, here are decompositions:

7 + 31524013 = 31524020
67 + 31523953 = 31524020
79 + 31523941 = 31524020
103 + 31523917 = 31524020
139 + 31523881 = 31524020
181 + 31523839 = 31524020
271 + 31523749 = 31524020
313 + 31523707 = 31524020

Showing the first eight; more decompositions exist.
