Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444958, here are decompositions:

19 + 31444939 = 31444958
67 + 31444891 = 31444958
79 + 31444879 = 31444958
151 + 31444807 = 31444958
157 + 31444801 = 31444958
199 + 31444759 = 31444958
241 + 31444717 = 31444958
277 + 31444681 = 31444958

Showing the first eight; more decompositions exist.
