Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525272, here are decompositions:

5 + 31525267 = 31525272
11 + 31525261 = 31525272
29 + 31525243 = 31525272
43 + 31525229 = 31525272
59 + 31525213 = 31525272
61 + 31525211 = 31525272
71 + 31525201 = 31525272
89 + 31525183 = 31525272

Showing the first eight; more decompositions exist.
