Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524180, here are decompositions:

13 + 31524167 = 31524180
19 + 31524161 = 31524180
47 + 31524133 = 31524180
73 + 31524107 = 31524180
89 + 31524091 = 31524180
131 + 31524049 = 31524180
137 + 31524043 = 31524180
157 + 31524023 = 31524180

Showing the first eight; more decompositions exist.
