Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625112, here are decompositions:

53 + 31625059 = 31625112
73 + 31625039 = 31625112
173 + 31624939 = 31625112
191 + 31624921 = 31625112
251 + 31624861 = 31625112
263 + 31624849 = 31625112
283 + 31624829 = 31625112
313 + 31624799 = 31625112

Showing the first eight; more decompositions exist.
