Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513314, here are decompositions:

5 + 31513309 = 31513314
11 + 31513303 = 31513314
101 + 31513213 = 31513314
113 + 31513201 = 31513314
127 + 31513187 = 31513314
167 + 31513147 = 31513314
191 + 31513123 = 31513314
197 + 31513117 = 31513314

Showing the first eight; more decompositions exist.
