Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537884, here are decompositions:

13 + 31537871 = 31537884
23 + 31537861 = 31537884
41 + 31537843 = 31537884
47 + 31537837 = 31537884
61 + 31537823 = 31537884
137 + 31537747 = 31537884
163 + 31537721 = 31537884
167 + 31537717 = 31537884

Showing the first eight; more decompositions exist.
