Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525464, here are decompositions:

17 + 31525447 = 31525464
43 + 31525421 = 31525464
67 + 31525397 = 31525464
97 + 31525367 = 31525464
181 + 31525283 = 31525464
197 + 31525267 = 31525464
251 + 31525213 = 31525464
263 + 31525201 = 31525464

Showing the first eight; more decompositions exist.
