Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620974, here are decompositions:

31 + 31620943 = 31620974
37 + 31620937 = 31620974
43 + 31620931 = 31620974
103 + 31620871 = 31620974
181 + 31620793 = 31620974
211 + 31620763 = 31620974
223 + 31620751 = 31620974
241 + 31620733 = 31620974

Showing the first eight; more decompositions exist.
