Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525080, here are decompositions:

43 + 31525037 = 31525080
53 + 31525027 = 31525080
73 + 31525007 = 31525080
89 + 31524991 = 31525080
113 + 31524967 = 31525080
241 + 31524839 = 31525080
271 + 31524809 = 31525080
283 + 31524797 = 31525080

Showing the first eight; more decompositions exist.
