Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525260, here are decompositions:

17 + 31525243 = 31525260
31 + 31525229 = 31525260
47 + 31525213 = 31525260
59 + 31525201 = 31525260
83 + 31525177 = 31525260
97 + 31525163 = 31525260
139 + 31525121 = 31525260
157 + 31525103 = 31525260

Showing the first eight; more decompositions exist.
