Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601050, here are decompositions:

167 + 31600883 = 31601050
191 + 31600859 = 31601050
227 + 31600823 = 31601050
233 + 31600817 = 31601050
251 + 31600799 = 31601050
317 + 31600733 = 31601050
347 + 31600703 = 31601050
431 + 31600619 = 31601050

Showing the first eight; more decompositions exist.
