Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525404, here are decompositions:

7 + 31525397 = 31525404
37 + 31525367 = 31525404
61 + 31525343 = 31525404
73 + 31525331 = 31525404
137 + 31525267 = 31525404
191 + 31525213 = 31525404
193 + 31525211 = 31525404
227 + 31525177 = 31525404

Showing the first eight; more decompositions exist.
