Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539234, here are decompositions:

5 + 31539229 = 31539234
43 + 31539191 = 31539234
71 + 31539163 = 31539234
151 + 31539083 = 31539234
173 + 31539061 = 31539234
191 + 31539043 = 31539234
227 + 31539007 = 31539234
283 + 31538951 = 31539234

Showing the first eight; more decompositions exist.
