Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526086, here are decompositions:

3 + 31526083 = 31526086
17 + 31526069 = 31526086
23 + 31526063 = 31526086
29 + 31526057 = 31526086
167 + 31525919 = 31526086
173 + 31525913 = 31526086
197 + 31525889 = 31526086
269 + 31525817 = 31526086

Showing the first eight; more decompositions exist.
