Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537896, here are decompositions:

7 + 31537889 = 31537896
37 + 31537859 = 31537896
53 + 31537843 = 31537896
59 + 31537837 = 31537896
73 + 31537823 = 31537896
149 + 31537747 = 31537896
179 + 31537717 = 31537896
293 + 31537603 = 31537896

Showing the first eight; more decompositions exist.
