Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484814, here are decompositions:

13 + 31484801 = 31484814
17 + 31484797 = 31484814
37 + 31484777 = 31484814
43 + 31484771 = 31484814
61 + 31484753 = 31484814
73 + 31484741 = 31484814
103 + 31484711 = 31484814
167 + 31484647 = 31484814

Showing the first eight; more decompositions exist.
