Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483070, here are decompositions:

19 + 31483051 = 31483070
67 + 31483003 = 31483070
79 + 31482991 = 31483070
97 + 31482973 = 31483070
163 + 31482907 = 31483070
181 + 31482889 = 31483070
211 + 31482859 = 31483070
271 + 31482799 = 31483070

Showing the first eight; more decompositions exist.
