Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525424, here are decompositions:

3 + 31525421 = 31525424
157 + 31525267 = 31525424
163 + 31525261 = 31525424
181 + 31525243 = 31525424
211 + 31525213 = 31525424
223 + 31525201 = 31525424
241 + 31525183 = 31525424
397 + 31525027 = 31525424

Showing the first eight; more decompositions exist.
