Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444844, here are decompositions:

7 + 31444837 = 31444844
31 + 31444813 = 31444844
37 + 31444807 = 31444844
43 + 31444801 = 31444844
73 + 31444771 = 31444844
127 + 31444717 = 31444844
163 + 31444681 = 31444844
271 + 31444573 = 31444844

Showing the first eight; more decompositions exist.
