Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544188, here are decompositions:

17 + 31544171 = 31544188
89 + 31544099 = 31544188
131 + 31544057 = 31544188
149 + 31544039 = 31544188
167 + 31544021 = 31544188
191 + 31543997 = 31544188
197 + 31543991 = 31544188
227 + 31543961 = 31544188

Showing the first eight; more decompositions exist.
