Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525122, here are decompositions:

19 + 31525103 = 31525122
131 + 31524991 = 31525122
229 + 31524893 = 31525122
283 + 31524839 = 31525122
313 + 31524809 = 31525122
331 + 31524791 = 31525122
359 + 31524763 = 31525122
401 + 31524721 = 31525122

Showing the first eight; more decompositions exist.
