Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454916, here are decompositions:

7 + 31454909 = 31454916
13 + 31454903 = 31454916
43 + 31454873 = 31454916
79 + 31454837 = 31454916
89 + 31454827 = 31454916
107 + 31454809 = 31454916
179 + 31454737 = 31454916
263 + 31454653 = 31454916

Showing the first eight; more decompositions exist.
