Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493032, here are decompositions:

3 + 31493029 = 31493032
23 + 31493009 = 31493032
41 + 31492991 = 31493032
89 + 31492943 = 31493032
173 + 31492859 = 31493032
191 + 31492841 = 31493032
251 + 31492781 = 31493032
281 + 31492751 = 31493032

Showing the first eight; more decompositions exist.
