Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525484, here are decompositions:

7 + 31525477 = 31525484
37 + 31525447 = 31525484
223 + 31525261 = 31525484
241 + 31525243 = 31525484
271 + 31525213 = 31525484
283 + 31525201 = 31525484
307 + 31525177 = 31525484
457 + 31525027 = 31525484

Showing the first eight; more decompositions exist.
