Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532458, here are decompositions:

29 + 31532429 = 31532458
179 + 31532279 = 31532458
197 + 31532261 = 31532458
239 + 31532219 = 31532458
317 + 31532141 = 31532458
491 + 31531967 = 31532458
641 + 31531817 = 31532458
809 + 31531649 = 31532458

Showing the first eight; more decompositions exist.
