Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620944, here are decompositions:

7 + 31620937 = 31620944
13 + 31620931 = 31620944
73 + 31620871 = 31620944
151 + 31620793 = 31620944
181 + 31620763 = 31620944
193 + 31620751 = 31620944
211 + 31620733 = 31620944
283 + 31620661 = 31620944

Showing the first eight; more decompositions exist.
