Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526118, here are decompositions:

31 + 31526087 = 31526118
61 + 31526057 = 31526118
67 + 31526051 = 31526118
97 + 31526021 = 31526118
137 + 31525981 = 31526118
167 + 31525951 = 31526118
191 + 31525927 = 31526118
199 + 31525919 = 31526118

Showing the first eight; more decompositions exist.
