Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525384, here are decompositions:

5 + 31525379 = 31525384
17 + 31525367 = 31525384
41 + 31525343 = 31525384
53 + 31525331 = 31525384
101 + 31525283 = 31525384
173 + 31525211 = 31525384
257 + 31525127 = 31525384
263 + 31525121 = 31525384

Showing the first eight; more decompositions exist.
