Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526898, here are decompositions:

5 + 31526893 = 31526898
17 + 31526881 = 31526898
19 + 31526879 = 31526898
79 + 31526819 = 31526898
89 + 31526809 = 31526898
107 + 31526791 = 31526898
127 + 31526771 = 31526898
149 + 31526749 = 31526898

Showing the first eight; more decompositions exist.
