Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484874, here are decompositions:

11 + 31484863 = 31484874
37 + 31484837 = 31484874
53 + 31484821 = 31484874
73 + 31484801 = 31484874
97 + 31484777 = 31484874
103 + 31484771 = 31484874
163 + 31484711 = 31484874
227 + 31484647 = 31484874

Showing the first eight; more decompositions exist.
