Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525026, here are decompositions:

19 + 31525007 = 31525026
37 + 31524989 = 31525026
59 + 31524967 = 31525026
89 + 31524937 = 31525026
163 + 31524863 = 31525026
229 + 31524797 = 31525026
233 + 31524793 = 31525026
263 + 31524763 = 31525026

Showing the first eight; more decompositions exist.
