Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532108, here are decompositions:

19 + 31532089 = 31532108
37 + 31532071 = 31532108
199 + 31531909 = 31532108
691 + 31531417 = 31532108
709 + 31531399 = 31532108
739 + 31531369 = 31532108
859 + 31531249 = 31532108
991 + 31531117 = 31532108

Showing the first eight; more decompositions exist.
