Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483588, here are decompositions:

5 + 31483583 = 31483588
11 + 31483577 = 31483588
41 + 31483547 = 31483588
131 + 31483457 = 31483588
197 + 31483391 = 31483588
281 + 31483307 = 31483588
359 + 31483229 = 31483588
419 + 31483169 = 31483588

Showing the first eight; more decompositions exist.
