Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627316, here are decompositions:

13 + 31627303 = 31627316
67 + 31627249 = 31627316
73 + 31627243 = 31627316
79 + 31627237 = 31627316
283 + 31627033 = 31627316
337 + 31626979 = 31627316
349 + 31626967 = 31627316
373 + 31626943 = 31627316

Showing the first eight; more decompositions exist.
