Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525230, here are decompositions:

17 + 31525213 = 31525230
19 + 31525211 = 31525230
29 + 31525201 = 31525230
47 + 31525183 = 31525230
53 + 31525177 = 31525230
67 + 31525163 = 31525230
103 + 31525127 = 31525230
109 + 31525121 = 31525230

Showing the first eight; more decompositions exist.
