Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567616, here are decompositions:

13 + 31567603 = 31567616
103 + 31567513 = 31567616
337 + 31567279 = 31567616
349 + 31567267 = 31567616
397 + 31567219 = 31567616
463 + 31567153 = 31567616
643 + 31566973 = 31567616
823 + 31566793 = 31567616

Showing the first eight; more decompositions exist.
