Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567254, here are decompositions:

13 + 31567241 = 31567254
23 + 31567231 = 31567254
41 + 31567213 = 31567254
97 + 31567157 = 31567254
101 + 31567153 = 31567254
163 + 31567091 = 31567254
167 + 31567087 = 31567254
211 + 31567043 = 31567254

Showing the first eight; more decompositions exist.
