Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525176, here are decompositions:

13 + 31525163 = 31525176
73 + 31525103 = 31525176
139 + 31525037 = 31525176
149 + 31525027 = 31525176
239 + 31524937 = 31525176
283 + 31524893 = 31525176
313 + 31524863 = 31525176
337 + 31524839 = 31525176

Showing the first eight; more decompositions exist.
