Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528294, here are decompositions:

3 + 31528291 = 31528294
11 + 31528283 = 31528294
53 + 31528241 = 31528294
137 + 31528157 = 31528294
167 + 31528127 = 31528294
173 + 31528121 = 31528294
191 + 31528103 = 31528294
227 + 31528067 = 31528294

Showing the first eight; more decompositions exist.
