Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444998, here are decompositions:

5 + 31444993 = 31444998
59 + 31444939 = 31444998
61 + 31444937 = 31444998
97 + 31444901 = 31444998
107 + 31444891 = 31444998
127 + 31444871 = 31444998
191 + 31444807 = 31444998
197 + 31444801 = 31444998

Showing the first eight; more decompositions exist.
