Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627212, here are decompositions:

11 + 31627201 = 31627212
61 + 31627151 = 31627212
79 + 31627133 = 31627212
139 + 31627073 = 31627212
179 + 31627033 = 31627212
233 + 31626979 = 31627212
269 + 31626943 = 31627212
313 + 31626899 = 31627212

Showing the first eight; more decompositions exist.
