Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567526, here are decompositions:

13 + 31567513 = 31567526
97 + 31567429 = 31567526
157 + 31567369 = 31567526
229 + 31567297 = 31567526
307 + 31567219 = 31567526
313 + 31567213 = 31567526
373 + 31567153 = 31567526
439 + 31567087 = 31567526

Showing the first eight; more decompositions exist.
