Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523098, here are decompositions:

17 + 31523081 = 31523098
71 + 31523027 = 31523098
137 + 31522961 = 31523098
197 + 31522901 = 31523098
251 + 31522847 = 31523098
557 + 31522541 = 31523098
569 + 31522529 = 31523098
647 + 31522451 = 31523098

Showing the first eight; more decompositions exist.
