Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484046, here are decompositions:

67 + 31483979 = 31484046
89 + 31483957 = 31484046
127 + 31483919 = 31484046
157 + 31483889 = 31484046
163 + 31483883 = 31484046
227 + 31483819 = 31484046
239 + 31483807 = 31484046
257 + 31483789 = 31484046

Showing the first eight; more decompositions exist.
