Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598884, here are decompositions:

11 + 31598873 = 31598884
17 + 31598867 = 31598884
101 + 31598783 = 31598884
113 + 31598771 = 31598884
131 + 31598753 = 31598884
167 + 31598717 = 31598884
197 + 31598687 = 31598884
293 + 31598591 = 31598884

Showing the first eight; more decompositions exist.
