Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620950, here are decompositions:

3 + 31620947 = 31620950
7 + 31620943 = 31620950
13 + 31620937 = 31620950
19 + 31620931 = 31620950
79 + 31620871 = 31620950
157 + 31620793 = 31620950
199 + 31620751 = 31620950
241 + 31620709 = 31620950

Showing the first eight; more decompositions exist.
