Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625958, here are decompositions:

5 + 31625953 = 31625958
19 + 31625939 = 31625958
41 + 31625917 = 31625958
47 + 31625911 = 31625958
109 + 31625849 = 31625958
137 + 31625821 = 31625958
139 + 31625819 = 31625958
151 + 31625807 = 31625958

Showing the first eight; more decompositions exist.
