Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567424, here are decompositions:

13 + 31567411 = 31567424
127 + 31567297 = 31567424
157 + 31567267 = 31567424
193 + 31567231 = 31567424
211 + 31567213 = 31567424
271 + 31567153 = 31567424
337 + 31567087 = 31567424
457 + 31566967 = 31567424

Showing the first eight; more decompositions exist.
