Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625552, here are decompositions:

43 + 31625509 = 31625552
151 + 31625401 = 31625552
271 + 31625281 = 31625552
373 + 31625179 = 31625552
421 + 31625131 = 31625552
601 + 31624951 = 31625552
613 + 31624939 = 31625552
631 + 31624921 = 31625552

Showing the first eight; more decompositions exist.
