Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483086, here are decompositions:

17 + 31483069 = 31483086
83 + 31483003 = 31483086
109 + 31482977 = 31483086
113 + 31482973 = 31483086
139 + 31482947 = 31483086
179 + 31482907 = 31483086
197 + 31482889 = 31483086
227 + 31482859 = 31483086

Showing the first eight; more decompositions exist.
