Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525250, here are decompositions:

7 + 31525243 = 31525250
37 + 31525213 = 31525250
67 + 31525183 = 31525250
73 + 31525177 = 31525250
223 + 31525027 = 31525250
283 + 31524967 = 31525250
313 + 31524937 = 31525250
457 + 31524793 = 31525250

Showing the first eight; more decompositions exist.
