Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444908, here are decompositions:

7 + 31444901 = 31444908
17 + 31444891 = 31444908
29 + 31444879 = 31444908
31 + 31444877 = 31444908
37 + 31444871 = 31444908
71 + 31444837 = 31444908
101 + 31444807 = 31444908
107 + 31444801 = 31444908

Showing the first eight; more decompositions exist.
