Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444874, here are decompositions:

3 + 31444871 = 31444874
31 + 31444843 = 31444874
37 + 31444837 = 31444874
61 + 31444813 = 31444874
67 + 31444807 = 31444874
73 + 31444801 = 31444874
103 + 31444771 = 31444874
151 + 31444723 = 31444874

Showing the first eight; more decompositions exist.
