Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525468, here are decompositions:

47 + 31525421 = 31525468
71 + 31525397 = 31525468
89 + 31525379 = 31525468
101 + 31525367 = 31525468
137 + 31525331 = 31525468
179 + 31525289 = 31525468
239 + 31525229 = 31525468
257 + 31525211 = 31525468

Showing the first eight; more decompositions exist.
