Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534432, here are decompositions:

3 + 31534429 = 31534432
5 + 31534427 = 31534432
89 + 31534343 = 31534432
131 + 31534301 = 31534432
191 + 31534241 = 31534432
233 + 31534199 = 31534432
263 + 31534169 = 31534432
311 + 31534121 = 31534432

Showing the first eight; more decompositions exist.
