Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483946, here are decompositions:

19 + 31483927 = 31483946
127 + 31483819 = 31483946
139 + 31483807 = 31483946
157 + 31483789 = 31483946
223 + 31483723 = 31483946
283 + 31483663 = 31483946
349 + 31483597 = 31483946
397 + 31483549 = 31483946

Showing the first eight; more decompositions exist.
