Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567532, here are decompositions:

19 + 31567513 = 31567532
103 + 31567429 = 31567532
163 + 31567369 = 31567532
313 + 31567219 = 31567532
379 + 31567153 = 31567532
613 + 31566919 = 31567532
631 + 31566901 = 31567532
739 + 31566793 = 31567532

Showing the first eight; more decompositions exist.
