Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627002, here are decompositions:

23 + 31626979 = 31627002
59 + 31626943 = 31627002
103 + 31626899 = 31627002
109 + 31626893 = 31627002
163 + 31626839 = 31627002
293 + 31626709 = 31627002
311 + 31626691 = 31627002
313 + 31626689 = 31627002

Showing the first eight; more decompositions exist.
