Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567382, here are decompositions:

13 + 31567369 = 31567382
103 + 31567279 = 31567382
151 + 31567231 = 31567382
163 + 31567219 = 31567382
229 + 31567153 = 31567382
409 + 31566973 = 31567382
463 + 31566919 = 31567382
619 + 31566763 = 31567382

Showing the first eight; more decompositions exist.
