Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532132, here are decompositions:

19 + 31532113 = 31532132
43 + 31532089 = 31532132
61 + 31532071 = 31532132
211 + 31531921 = 31532132
223 + 31531909 = 31532132
661 + 31531471 = 31532132
733 + 31531399 = 31532132
829 + 31531303 = 31532132

Showing the first eight; more decompositions exist.
