Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525182, here are decompositions:

5 + 31525177 = 31525182
19 + 31525163 = 31525182
61 + 31525121 = 31525182
79 + 31525103 = 31525182
151 + 31525031 = 31525182
191 + 31524991 = 31525182
193 + 31524989 = 31525182
373 + 31524809 = 31525182

Showing the first eight; more decompositions exist.
