Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483182, here are decompositions:

13 + 31483169 = 31483182
19 + 31483163 = 31483182
89 + 31483093 = 31483182
113 + 31483069 = 31483182
131 + 31483051 = 31483182
179 + 31483003 = 31483182
191 + 31482991 = 31483182
293 + 31482889 = 31483182

Showing the first eight; more decompositions exist.
