Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444710, here are decompositions:

19 + 31444691 = 31444710
29 + 31444681 = 31444710
61 + 31444649 = 31444710
67 + 31444643 = 31444710
79 + 31444631 = 31444710
83 + 31444627 = 31444710
137 + 31444573 = 31444710
151 + 31444559 = 31444710

Showing the first eight; more decompositions exist.
