Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444904, here are decompositions:

3 + 31444901 = 31444904
13 + 31444891 = 31444904
61 + 31444843 = 31444904
67 + 31444837 = 31444904
97 + 31444807 = 31444904
103 + 31444801 = 31444904
181 + 31444723 = 31444904
223 + 31444681 = 31444904

Showing the first eight; more decompositions exist.
