Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483548, here are decompositions:

79 + 31483469 = 31483548
101 + 31483447 = 31483548
157 + 31483391 = 31483548
179 + 31483369 = 31483548
197 + 31483351 = 31483548
241 + 31483307 = 31483548
311 + 31483237 = 31483548
331 + 31483217 = 31483548

Showing the first eight; more decompositions exist.
