Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567524, here are decompositions:

11 + 31567513 = 31567524
13 + 31567511 = 31567524
73 + 31567451 = 31567524
97 + 31567427 = 31567524
113 + 31567411 = 31567524
127 + 31567397 = 31567524
211 + 31567313 = 31567524
227 + 31567297 = 31567524

Showing the first eight; more decompositions exist.
