Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514432, here are decompositions:

3 + 31514429 = 31514432
13 + 31514419 = 31514432
31 + 31514401 = 31514432
193 + 31514239 = 31514432
211 + 31514221 = 31514432
241 + 31514191 = 31514432
283 + 31514149 = 31514432
331 + 31514101 = 31514432

Showing the first eight; more decompositions exist.
