Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483198, here are decompositions:

29 + 31483169 = 31483198
101 + 31483097 = 31483198
137 + 31483061 = 31483198
251 + 31482947 = 31483198
359 + 31482839 = 31483198
419 + 31482779 = 31483198
491 + 31482707 = 31483198
557 + 31482641 = 31483198

Showing the first eight; more decompositions exist.
