Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524072, here are decompositions:

23 + 31524049 = 31524072
29 + 31524043 = 31524072
59 + 31524013 = 31524072
61 + 31524011 = 31524072
131 + 31523941 = 31524072
191 + 31523881 = 31524072
233 + 31523839 = 31524072
269 + 31523803 = 31524072

Showing the first eight; more decompositions exist.
