Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483232, here are decompositions:

3 + 31483229 = 31483232
19 + 31483213 = 31483232
139 + 31483093 = 31483232
163 + 31483069 = 31483232
181 + 31483051 = 31483232
229 + 31483003 = 31483232
241 + 31482991 = 31483232
373 + 31482859 = 31483232

Showing the first eight; more decompositions exist.
