Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625058, here are decompositions:

19 + 31625039 = 31625058
79 + 31624979 = 31625058
107 + 31624951 = 31625058
131 + 31624927 = 31625058
137 + 31624921 = 31625058
151 + 31624907 = 31625058
197 + 31624861 = 31625058
229 + 31624829 = 31625058

Showing the first eight; more decompositions exist.
