Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525150, here are decompositions:

23 + 31525127 = 31525150
29 + 31525121 = 31525150
47 + 31525103 = 31525150
113 + 31525037 = 31525150
257 + 31524893 = 31525150
311 + 31524839 = 31525150
353 + 31524797 = 31525150
359 + 31524791 = 31525150

Showing the first eight; more decompositions exist.
