Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483956, here are decompositions:

29 + 31483927 = 31483956
37 + 31483919 = 31483956
43 + 31483913 = 31483956
67 + 31483889 = 31483956
73 + 31483883 = 31483956
79 + 31483877 = 31483956
137 + 31483819 = 31483956
149 + 31483807 = 31483956

Showing the first eight; more decompositions exist.
