Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525298, here are decompositions:

19 + 31525279 = 31525298
31 + 31525267 = 31525298
37 + 31525261 = 31525298
97 + 31525201 = 31525298
271 + 31525027 = 31525298
307 + 31524991 = 31525298
331 + 31524967 = 31525298
577 + 31524721 = 31525298

Showing the first eight; more decompositions exist.
