Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525308, here are decompositions:

19 + 31525289 = 31525308
29 + 31525279 = 31525308
41 + 31525267 = 31525308
47 + 31525261 = 31525308
79 + 31525229 = 31525308
97 + 31525211 = 31525308
107 + 31525201 = 31525308
131 + 31525177 = 31525308

Showing the first eight; more decompositions exist.
