Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550950, here are decompositions:

3 + 31550947 = 31550950
29 + 31550921 = 31550950
71 + 31550879 = 31550950
83 + 31550867 = 31550950
113 + 31550837 = 31550950
149 + 31550801 = 31550950
227 + 31550723 = 31550950
239 + 31550711 = 31550950

Showing the first eight; more decompositions exist.
