Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625352, here are decompositions:

71 + 31625281 = 31625352
89 + 31625263 = 31625352
173 + 31625179 = 31625352
293 + 31625059 = 31625352
313 + 31625039 = 31625352
373 + 31624979 = 31625352
401 + 31624951 = 31625352
431 + 31624921 = 31625352

Showing the first eight; more decompositions exist.
