Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525248, here are decompositions:

5 + 31525243 = 31525248
19 + 31525229 = 31525248
37 + 31525211 = 31525248
47 + 31525201 = 31525248
71 + 31525177 = 31525248
127 + 31525121 = 31525248
211 + 31525037 = 31525248
241 + 31525007 = 31525248

Showing the first eight; more decompositions exist.
