Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525372, here are decompositions:

5 + 31525367 = 31525372
29 + 31525343 = 31525372
41 + 31525331 = 31525372
83 + 31525289 = 31525372
89 + 31525283 = 31525372
251 + 31525121 = 31525372
269 + 31525103 = 31525372
383 + 31524989 = 31525372

Showing the first eight; more decompositions exist.
