Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444922, here are decompositions:

31 + 31444891 = 31444922
43 + 31444879 = 31444922
79 + 31444843 = 31444922
109 + 31444813 = 31444922
151 + 31444771 = 31444922
163 + 31444759 = 31444922
199 + 31444723 = 31444922
241 + 31444681 = 31444922

Showing the first eight; more decompositions exist.
