Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525516, here are decompositions:

17 + 31525499 = 31525516
137 + 31525379 = 31525516
149 + 31525367 = 31525516
173 + 31525343 = 31525516
227 + 31525289 = 31525516
233 + 31525283 = 31525516
353 + 31525163 = 31525516
389 + 31525127 = 31525516

Showing the first eight; more decompositions exist.
