Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539232, here are decompositions:

3 + 31539229 = 31539232
41 + 31539191 = 31539232
89 + 31539143 = 31539232
149 + 31539083 = 31539232
281 + 31538951 = 31539232
443 + 31538789 = 31539232
479 + 31538753 = 31539232
503 + 31538729 = 31539232

Showing the first eight; more decompositions exist.
