Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444744, here are decompositions:

17 + 31444727 = 31444744
53 + 31444691 = 31444744
83 + 31444661 = 31444744
101 + 31444643 = 31444744
113 + 31444631 = 31444744
197 + 31444547 = 31444744
431 + 31444313 = 31444744
503 + 31444241 = 31444744

Showing the first eight; more decompositions exist.
