Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463950, here are decompositions:

29 + 31463921 = 31463950
41 + 31463909 = 31463950
53 + 31463897 = 31463950
59 + 31463891 = 31463950
71 + 31463879 = 31463950
101 + 31463849 = 31463950
107 + 31463843 = 31463950
191 + 31463759 = 31463950

Showing the first eight; more decompositions exist.
