Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625102, here are decompositions:

43 + 31625059 = 31625102
151 + 31624951 = 31625102
163 + 31624939 = 31625102
181 + 31624921 = 31625102
241 + 31624861 = 31625102
349 + 31624753 = 31625102
463 + 31624639 = 31625102
673 + 31624429 = 31625102

Showing the first eight; more decompositions exist.
