Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444916, here are decompositions:

37 + 31444879 = 31444916
73 + 31444843 = 31444916
79 + 31444837 = 31444916
103 + 31444813 = 31444916
109 + 31444807 = 31444916
127 + 31444789 = 31444916
157 + 31444759 = 31444916
193 + 31444723 = 31444916

Showing the first eight; more decompositions exist.
