Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567604, here are decompositions:

193 + 31567411 = 31567604
307 + 31567297 = 31567604
337 + 31567267 = 31567604
373 + 31567231 = 31567604
631 + 31566973 = 31567604
787 + 31566817 = 31567604
811 + 31566793 = 31567604
1063 + 31566541 = 31567604

Showing the first eight; more decompositions exist.
