Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598898, here are decompositions:

11 + 31598887 = 31598898
31 + 31598867 = 31598898
41 + 31598857 = 31598898
59 + 31598839 = 31598898
109 + 31598789 = 31598898
127 + 31598771 = 31598898
181 + 31598717 = 31598898
197 + 31598701 = 31598898

Showing the first eight; more decompositions exist.
