Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566476, here are decompositions:

3 + 31566473 = 31566476
79 + 31566397 = 31566476
127 + 31566349 = 31566476
229 + 31566247 = 31566476
307 + 31566169 = 31566476
397 + 31566079 = 31566476
433 + 31566043 = 31566476
457 + 31566019 = 31566476

Showing the first eight; more decompositions exist.
