Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567798, here are decompositions:

29 + 31567769 = 31567798
89 + 31567709 = 31567798
149 + 31567649 = 31567798
179 + 31567619 = 31567798
239 + 31567559 = 31567798
347 + 31567451 = 31567798
401 + 31567397 = 31567798
557 + 31567241 = 31567798

Showing the first eight; more decompositions exist.
