Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532162, here are decompositions:

73 + 31532089 = 31532162
241 + 31531921 = 31532162
349 + 31531813 = 31532162
523 + 31531639 = 31532162
691 + 31531471 = 31532162
709 + 31531453 = 31532162
859 + 31531303 = 31532162
1063 + 31531099 = 31532162

Showing the first eight; more decompositions exist.
