Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567454, here are decompositions:

3 + 31567451 = 31567454
43 + 31567411 = 31567454
157 + 31567297 = 31567454
223 + 31567231 = 31567454
241 + 31567213 = 31567454
367 + 31567087 = 31567454
487 + 31566967 = 31567454
661 + 31566793 = 31567454

Showing the first eight; more decompositions exist.
