Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627136, here are decompositions:

3 + 31627133 = 31627136
67 + 31627069 = 31627136
103 + 31627033 = 31627136
109 + 31627027 = 31627136
157 + 31626979 = 31627136
193 + 31626943 = 31627136
349 + 31626787 = 31627136
547 + 31626589 = 31627136

Showing the first eight; more decompositions exist.
