Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598910, here are decompositions:

23 + 31598887 = 31598910
37 + 31598873 = 31598910
43 + 31598867 = 31598910
47 + 31598863 = 31598910
53 + 31598857 = 31598910
71 + 31598839 = 31598910
127 + 31598783 = 31598910
131 + 31598779 = 31598910

Showing the first eight; more decompositions exist.
