Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627734, here are decompositions:

7 + 31627727 = 31627734
13 + 31627721 = 31627734
107 + 31627627 = 31627734
157 + 31627577 = 31627734
167 + 31627567 = 31627734
191 + 31627543 = 31627734
197 + 31627537 = 31627734
223 + 31627511 = 31627734

Showing the first eight; more decompositions exist.
