Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525244, here are decompositions:

31 + 31525213 = 31525244
43 + 31525201 = 31525244
61 + 31525183 = 31525244
67 + 31525177 = 31525244
277 + 31524967 = 31525244
307 + 31524937 = 31525244
523 + 31524721 = 31525244
571 + 31524673 = 31525244

Showing the first eight; more decompositions exist.
