Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606932, here are decompositions:

13 + 31606919 = 31606932
29 + 31606903 = 31606932
53 + 31606879 = 31606932
103 + 31606829 = 31606932
179 + 31606753 = 31606932
191 + 31606741 = 31606932
229 + 31606703 = 31606932
241 + 31606691 = 31606932

Showing the first eight; more decompositions exist.
