Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601896, here are decompositions:

5 + 31601891 = 31601896
23 + 31601873 = 31601896
47 + 31601849 = 31601896
59 + 31601837 = 31601896
113 + 31601783 = 31601896
173 + 31601723 = 31601896
197 + 31601699 = 31601896
383 + 31601513 = 31601896

Showing the first eight; more decompositions exist.
