Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444854, here are decompositions:

11 + 31444843 = 31444854
17 + 31444837 = 31444854
41 + 31444813 = 31444854
47 + 31444807 = 31444854
53 + 31444801 = 31444854
83 + 31444771 = 31444854
127 + 31444727 = 31444854
131 + 31444723 = 31444854

Showing the first eight; more decompositions exist.
