Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484050, here are decompositions:

71 + 31483979 = 31484050
131 + 31483919 = 31484050
137 + 31483913 = 31484050
167 + 31483883 = 31484050
173 + 31483877 = 31484050
179 + 31483871 = 31484050
251 + 31483799 = 31484050
317 + 31483733 = 31484050

Showing the first eight; more decompositions exist.
