Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524832, here are decompositions:

23 + 31524809 = 31524832
41 + 31524791 = 31524832
191 + 31524641 = 31524832
263 + 31524569 = 31524832
809 + 31524023 = 31524832
821 + 31524011 = 31524832
1031 + 31523801 = 31524832
1163 + 31523669 = 31524832

Showing the first eight; more decompositions exist.
