Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510098, here are decompositions:

5 + 31510093 = 31510098
7 + 31510091 = 31510098
19 + 31510079 = 31510098
89 + 31510009 = 31510098
97 + 31510001 = 31510098
107 + 31509991 = 31510098
127 + 31509971 = 31510098
131 + 31509967 = 31510098

Showing the first eight; more decompositions exist.
