Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562316, here are decompositions:

17 + 31562299 = 31562316
43 + 31562273 = 31562316
53 + 31562263 = 31562316
59 + 31562257 = 31562316
73 + 31562243 = 31562316
103 + 31562213 = 31562316
179 + 31562137 = 31562316
197 + 31562119 = 31562316

Showing the first eight; more decompositions exist.
