Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484950, here are decompositions:

47 + 31484903 = 31484950
113 + 31484837 = 31484950
149 + 31484801 = 31484950
173 + 31484777 = 31484950
179 + 31484771 = 31484950
197 + 31484753 = 31484950
239 + 31484711 = 31484950
251 + 31484699 = 31484950

Showing the first eight; more decompositions exist.
