Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524260, here are decompositions:

3 + 31524257 = 31524260
37 + 31524223 = 31524260
67 + 31524193 = 31524260
127 + 31524133 = 31524260
211 + 31524049 = 31524260
307 + 31523953 = 31524260
379 + 31523881 = 31524260
409 + 31523851 = 31524260

Showing the first eight; more decompositions exist.
