Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567504, here are decompositions:

53 + 31567451 = 31567504
107 + 31567397 = 31567504
191 + 31567313 = 31567504
233 + 31567271 = 31567504
263 + 31567241 = 31567504
347 + 31567157 = 31567504
461 + 31567043 = 31567504
593 + 31566911 = 31567504

Showing the first eight; more decompositions exist.
