Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625024, here are decompositions:

73 + 31624951 = 31625024
97 + 31624927 = 31625024
103 + 31624921 = 31625024
163 + 31624861 = 31625024
241 + 31624783 = 31625024
271 + 31624753 = 31625024
283 + 31624741 = 31625024
307 + 31624717 = 31625024

Showing the first eight; more decompositions exist.
