Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532192, here are decompositions:

79 + 31532113 = 31532192
103 + 31532089 = 31532192
271 + 31531921 = 31532192
283 + 31531909 = 31532192
379 + 31531813 = 31532192
613 + 31531579 = 31532192
709 + 31531483 = 31532192
739 + 31531453 = 31532192

Showing the first eight; more decompositions exist.
