Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471410, here are decompositions:

13 + 31471397 = 31471410
23 + 31471387 = 31471410
37 + 31471373 = 31471410
53 + 31471357 = 31471410
79 + 31471331 = 31471410
193 + 31471217 = 31471410
197 + 31471213 = 31471410
239 + 31471171 = 31471410

Showing the first eight; more decompositions exist.
