Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513410, here are decompositions:

7 + 31513403 = 31513410
37 + 31513373 = 31513410
79 + 31513331 = 31513410
101 + 31513309 = 31513410
107 + 31513303 = 31513410
151 + 31513259 = 31513410
191 + 31513219 = 31513410
197 + 31513213 = 31513410

Showing the first eight; more decompositions exist.
