Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484968, here are decompositions:

131 + 31484837 = 31484968
167 + 31484801 = 31484968
191 + 31484777 = 31484968
197 + 31484771 = 31484968
227 + 31484741 = 31484968
257 + 31484711 = 31484968
269 + 31484699 = 31484968
701 + 31484267 = 31484968

Showing the first eight; more decompositions exist.
