Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536316, here are decompositions:

3 + 31536313 = 31536316
23 + 31536293 = 31536316
29 + 31536287 = 31536316
89 + 31536227 = 31536316
113 + 31536203 = 31536316
263 + 31536053 = 31536316
563 + 31535753 = 31536316
569 + 31535747 = 31536316

Showing the first eight; more decompositions exist.
