Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525698, here are decompositions:

11 + 31525687 = 31525698
41 + 31525657 = 31525698
47 + 31525651 = 31525698
89 + 31525609 = 31525698
97 + 31525601 = 31525698
109 + 31525589 = 31525698
131 + 31525567 = 31525698
199 + 31525499 = 31525698

Showing the first eight; more decompositions exist.
