Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567560, here are decompositions:

7 + 31567553 = 31567560
47 + 31567513 = 31567560
109 + 31567451 = 31567560
131 + 31567429 = 31567560
149 + 31567411 = 31567560
163 + 31567397 = 31567560
191 + 31567369 = 31567560
263 + 31567297 = 31567560

Showing the first eight; more decompositions exist.
