Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627764, here are decompositions:

11 + 31627753 = 31627764
13 + 31627751 = 31627764
37 + 31627727 = 31627764
43 + 31627721 = 31627764
137 + 31627627 = 31627764
163 + 31627601 = 31627764
191 + 31627573 = 31627764
197 + 31627567 = 31627764

Showing the first eight; more decompositions exist.
