Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567496, here are decompositions:

67 + 31567429 = 31567496
127 + 31567369 = 31567496
199 + 31567297 = 31567496
229 + 31567267 = 31567496
277 + 31567219 = 31567496
283 + 31567213 = 31567496
409 + 31567087 = 31567496
523 + 31566973 = 31567496

Showing the first eight; more decompositions exist.
