Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535316, here are decompositions:

5 + 31535311 = 31535316
53 + 31535263 = 31535316
83 + 31535233 = 31535316
89 + 31535227 = 31535316
97 + 31535219 = 31535316
103 + 31535213 = 31535316
173 + 31535143 = 31535316
193 + 31535123 = 31535316

Showing the first eight; more decompositions exist.
