Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627236, here are decompositions:

19 + 31627217 = 31627236
103 + 31627133 = 31627236
163 + 31627073 = 31627236
167 + 31627069 = 31627236
229 + 31627007 = 31627236
257 + 31626979 = 31627236
269 + 31626967 = 31627236
293 + 31626943 = 31627236

Showing the first eight; more decompositions exist.
