Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444698, here are decompositions:

7 + 31444691 = 31444698
17 + 31444681 = 31444698
37 + 31444661 = 31444698
67 + 31444631 = 31444698
71 + 31444627 = 31444698
107 + 31444591 = 31444698
139 + 31444559 = 31444698
151 + 31444547 = 31444698

Showing the first eight; more decompositions exist.
