Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525034, here are decompositions:

3 + 31525031 = 31525034
7 + 31525027 = 31525034
43 + 31524991 = 31525034
67 + 31524967 = 31525034
97 + 31524937 = 31525034
241 + 31524793 = 31525034
271 + 31524763 = 31525034
313 + 31524721 = 31525034

Showing the first eight; more decompositions exist.
