Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534916, here are decompositions:

3 + 31534913 = 31534916
37 + 31534879 = 31534916
43 + 31534873 = 31534916
97 + 31534819 = 31534916
163 + 31534753 = 31534916
373 + 31534543 = 31534916
433 + 31534483 = 31534916
487 + 31534429 = 31534916

Showing the first eight; more decompositions exist.
