Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526334, here are decompositions:

17 + 31526317 = 31526334
53 + 31526281 = 31526334
61 + 31526273 = 31526334
107 + 31526227 = 31526334
113 + 31526221 = 31526334
127 + 31526207 = 31526334
137 + 31526197 = 31526334
193 + 31526141 = 31526334

Showing the first eight; more decompositions exist.
