Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476144, here are decompositions:

31 + 31476113 = 31476144
47 + 31476097 = 31476144
71 + 31476073 = 31476144
113 + 31476031 = 31476144
127 + 31476017 = 31476144
131 + 31476013 = 31476144
181 + 31475963 = 31476144
191 + 31475953 = 31476144

Showing the first eight; more decompositions exist.
