Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627026, here are decompositions:

19 + 31627007 = 31627026
47 + 31626979 = 31627026
59 + 31626967 = 31627026
83 + 31626943 = 31627026
127 + 31626899 = 31627026
157 + 31626869 = 31627026
199 + 31626827 = 31627026
229 + 31626797 = 31627026

Showing the first eight; more decompositions exist.
