Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444946, here are decompositions:

7 + 31444939 = 31444946
67 + 31444879 = 31444946
103 + 31444843 = 31444946
109 + 31444837 = 31444946
139 + 31444807 = 31444946
157 + 31444789 = 31444946
223 + 31444723 = 31444946
229 + 31444717 = 31444946

Showing the first eight; more decompositions exist.
