Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567434, here are decompositions:

5 + 31567429 = 31567434
7 + 31567427 = 31567434
23 + 31567411 = 31567434
37 + 31567397 = 31567434
137 + 31567297 = 31567434
163 + 31567271 = 31567434
167 + 31567267 = 31567434
193 + 31567241 = 31567434

Showing the first eight; more decompositions exist.
