Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606052, here are decompositions:

3 + 31606049 = 31606052
139 + 31605913 = 31606052
229 + 31605823 = 31606052
241 + 31605811 = 31606052
271 + 31605781 = 31606052
433 + 31605619 = 31606052
613 + 31605439 = 31606052
691 + 31605361 = 31606052

Showing the first eight; more decompositions exist.
