Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532230, here are decompositions:

3 + 31532227 = 31532230
11 + 31532219 = 31532230
89 + 31532141 = 31532230
113 + 31532117 = 31532230
167 + 31532063 = 31532230
227 + 31532003 = 31532230
263 + 31531967 = 31532230
347 + 31531883 = 31532230

Showing the first eight; more decompositions exist.
