Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627170, here are decompositions:

19 + 31627151 = 31627170
37 + 31627133 = 31627170
79 + 31627091 = 31627170
97 + 31627073 = 31627170
101 + 31627069 = 31627170
137 + 31627033 = 31627170
163 + 31627007 = 31627170
191 + 31626979 = 31627170

Showing the first eight; more decompositions exist.
