Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525452, here are decompositions:

5 + 31525447 = 31525452
31 + 31525421 = 31525452
73 + 31525379 = 31525452
109 + 31525343 = 31525452
163 + 31525289 = 31525452
173 + 31525279 = 31525452
191 + 31525261 = 31525452
223 + 31525229 = 31525452

Showing the first eight; more decompositions exist.
