Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528354, here are decompositions:

5 + 31528349 = 31528354
17 + 31528337 = 31528354
41 + 31528313 = 31528354
71 + 31528283 = 31528354
113 + 31528241 = 31528354
197 + 31528157 = 31528354
227 + 31528127 = 31528354
233 + 31528121 = 31528354

Showing the first eight; more decompositions exist.
