Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484916, here are decompositions:

5 + 31484911 = 31484916
13 + 31484903 = 31484916
53 + 31484863 = 31484916
79 + 31484837 = 31484916
139 + 31484777 = 31484916
163 + 31484753 = 31484916
269 + 31484647 = 31484916
347 + 31484569 = 31484916

Showing the first eight; more decompositions exist.
