Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627694, here are decompositions:

67 + 31627627 = 31627694
127 + 31627567 = 31627694
151 + 31627543 = 31627694
157 + 31627537 = 31627694
193 + 31627501 = 31627694
211 + 31627483 = 31627694
283 + 31627411 = 31627694
337 + 31627357 = 31627694

Showing the first eight; more decompositions exist.
