Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525476, here are decompositions:

29 + 31525447 = 31525476
79 + 31525397 = 31525476
97 + 31525379 = 31525476
109 + 31525367 = 31525476
193 + 31525283 = 31525476
197 + 31525279 = 31525476
233 + 31525243 = 31525476
263 + 31525213 = 31525476

Showing the first eight; more decompositions exist.
