Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483408, here are decompositions:

17 + 31483391 = 31483408
101 + 31483307 = 31483408
179 + 31483229 = 31483408
191 + 31483217 = 31483408
239 + 31483169 = 31483408
311 + 31483097 = 31483408
347 + 31483061 = 31483408
431 + 31482977 = 31483408

Showing the first eight; more decompositions exist.
