Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444794, here are decompositions:

5 + 31444789 = 31444794
23 + 31444771 = 31444794
67 + 31444727 = 31444794
71 + 31444723 = 31444794
103 + 31444691 = 31444794
113 + 31444681 = 31444794
151 + 31444643 = 31444794
163 + 31444631 = 31444794

Showing the first eight; more decompositions exist.
