Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520476, here are decompositions:

23 + 31520453 = 31520476
59 + 31520417 = 31520476
83 + 31520393 = 31520476
89 + 31520387 = 31520476
137 + 31520339 = 31520476
167 + 31520309 = 31520476
233 + 31520243 = 31520476
359 + 31520117 = 31520476

Showing the first eight; more decompositions exist.
