Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444806, here are decompositions:

5 + 31444801 = 31444806
17 + 31444789 = 31444806
47 + 31444759 = 31444806
79 + 31444727 = 31444806
83 + 31444723 = 31444806
89 + 31444717 = 31444806
157 + 31444649 = 31444806
163 + 31444643 = 31444806

Showing the first eight; more decompositions exist.
