Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534328, here are decompositions:

31 + 31534297 = 31534328
97 + 31534231 = 31534328
211 + 31534117 = 31534328
271 + 31534057 = 31534328
277 + 31534051 = 31534328
349 + 31533979 = 31534328
379 + 31533949 = 31534328
409 + 31533919 = 31534328

Showing the first eight; more decompositions exist.
