Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525346, here are decompositions:

3 + 31525343 = 31525346
67 + 31525279 = 31525346
79 + 31525267 = 31525346
103 + 31525243 = 31525346
163 + 31525183 = 31525346
379 + 31524967 = 31525346
409 + 31524937 = 31525346
673 + 31524673 = 31525346

Showing the first eight; more decompositions exist.
