Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532156, here are decompositions:

43 + 31532113 = 31532156
67 + 31532089 = 31532156
577 + 31531579 = 31532156
673 + 31531483 = 31532156
739 + 31531417 = 31532156
757 + 31531399 = 31532156
787 + 31531369 = 31532156
853 + 31531303 = 31532156

Showing the first eight; more decompositions exist.
