Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625922, here are decompositions:

5 + 31625917 = 31625922
11 + 31625911 = 31625922
73 + 31625849 = 31625922
79 + 31625843 = 31625922
101 + 31625821 = 31625922
103 + 31625819 = 31625922
149 + 31625773 = 31625922
191 + 31625731 = 31625922

Showing the first eight; more decompositions exist.
