Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525470, here are decompositions:

23 + 31525447 = 31525470
73 + 31525397 = 31525470
103 + 31525367 = 31525470
127 + 31525343 = 31525470
139 + 31525331 = 31525470
181 + 31525289 = 31525470
191 + 31525279 = 31525470
227 + 31525243 = 31525470

Showing the first eight; more decompositions exist.
