Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525426, here are decompositions:

5 + 31525421 = 31525426
29 + 31525397 = 31525426
47 + 31525379 = 31525426
59 + 31525367 = 31525426
83 + 31525343 = 31525426
137 + 31525289 = 31525426
197 + 31525229 = 31525426
263 + 31525163 = 31525426

Showing the first eight; more decompositions exist.
