Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625268, here are decompositions:

5 + 31625263 = 31625268
7 + 31625261 = 31625268
89 + 31625179 = 31625268
137 + 31625131 = 31625268
211 + 31625057 = 31625268
229 + 31625039 = 31625268
317 + 31624951 = 31625268
347 + 31624921 = 31625268

Showing the first eight; more decompositions exist.
