Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444950, here are decompositions:

11 + 31444939 = 31444950
13 + 31444937 = 31444950
59 + 31444891 = 31444950
71 + 31444879 = 31444950
73 + 31444877 = 31444950
79 + 31444871 = 31444950
107 + 31444843 = 31444950
113 + 31444837 = 31444950

Showing the first eight; more decompositions exist.
