Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525454, here are decompositions:

7 + 31525447 = 31525454
193 + 31525261 = 31525454
211 + 31525243 = 31525454
241 + 31525213 = 31525454
271 + 31525183 = 31525454
277 + 31525177 = 31525454
463 + 31524991 = 31525454
487 + 31524967 = 31525454

Showing the first eight; more decompositions exist.
