Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598886, here are decompositions:

13 + 31598873 = 31598886
19 + 31598867 = 31598886
23 + 31598863 = 31598886
29 + 31598857 = 31598886
47 + 31598839 = 31598886
97 + 31598789 = 31598886
103 + 31598783 = 31598886
107 + 31598779 = 31598886

Showing the first eight; more decompositions exist.
