Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483258, here are decompositions:

29 + 31483229 = 31483258
41 + 31483217 = 31483258
89 + 31483169 = 31483258
197 + 31483061 = 31483258
281 + 31482977 = 31483258
311 + 31482947 = 31483258
419 + 31482839 = 31483258
479 + 31482779 = 31483258

Showing the first eight; more decompositions exist.
