Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625150, here are decompositions:

3 + 31625147 = 31625150
19 + 31625131 = 31625150
199 + 31624951 = 31625150
211 + 31624939 = 31625150
223 + 31624927 = 31625150
229 + 31624921 = 31625150
313 + 31624837 = 31625150
367 + 31624783 = 31625150

Showing the first eight; more decompositions exist.
