Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504916, here are decompositions:

7 + 31504909 = 31504916
13 + 31504903 = 31504916
43 + 31504873 = 31504916
97 + 31504819 = 31504916
349 + 31504567 = 31504916
463 + 31504453 = 31504916
613 + 31504303 = 31504916
727 + 31504189 = 31504916

Showing the first eight; more decompositions exist.
