Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532112, here are decompositions:

23 + 31532089 = 31532112
41 + 31532071 = 31532112
109 + 31532003 = 31532112
181 + 31531931 = 31532112
191 + 31531921 = 31532112
229 + 31531883 = 31532112
433 + 31531679 = 31532112
463 + 31531649 = 31532112

Showing the first eight; more decompositions exist.
