Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625070, here are decompositions:

11 + 31625059 = 31625070
13 + 31625057 = 31625070
31 + 31625039 = 31625070
131 + 31624939 = 31625070
149 + 31624921 = 31625070
163 + 31624907 = 31625070
233 + 31624837 = 31625070
241 + 31624829 = 31625070

Showing the first eight; more decompositions exist.
