Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483082, here are decompositions:

13 + 31483069 = 31483082
31 + 31483051 = 31483082
79 + 31483003 = 31483082
109 + 31482973 = 31483082
193 + 31482889 = 31483082
223 + 31482859 = 31483082
283 + 31482799 = 31483082
373 + 31482709 = 31483082

Showing the first eight; more decompositions exist.
