Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627256, here are decompositions:

7 + 31627249 = 31627256
13 + 31627243 = 31627256
19 + 31627237 = 31627256
223 + 31627033 = 31627256
229 + 31627027 = 31627256
277 + 31626979 = 31627256
313 + 31626943 = 31627256
373 + 31626883 = 31627256

Showing the first eight; more decompositions exist.
