Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567676, here are decompositions:

3 + 31567673 = 31567676
73 + 31567603 = 31567676
163 + 31567513 = 31567676
307 + 31567369 = 31567676
379 + 31567297 = 31567676
397 + 31567279 = 31567676
409 + 31567267 = 31567676
457 + 31567219 = 31567676

Showing the first eight; more decompositions exist.
