Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482970, here are decompositions:

23 + 31482947 = 31482970
131 + 31482839 = 31482970
137 + 31482833 = 31482970
149 + 31482821 = 31482970
191 + 31482779 = 31482970
227 + 31482743 = 31482970
263 + 31482707 = 31482970
353 + 31482617 = 31482970

Showing the first eight; more decompositions exist.
