Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625202, here are decompositions:

23 + 31625179 = 31625202
53 + 31625149 = 31625202
71 + 31625131 = 31625202
163 + 31625039 = 31625202
223 + 31624979 = 31625202
251 + 31624951 = 31625202
263 + 31624939 = 31625202
281 + 31624921 = 31625202

Showing the first eight; more decompositions exist.
