Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597932, here are decompositions:

5 + 31597927 = 31597932
19 + 31597913 = 31597932
53 + 31597879 = 31597932
59 + 31597873 = 31597932
89 + 31597843 = 31597932
109 + 31597823 = 31597932
131 + 31597801 = 31597932
139 + 31597793 = 31597932

Showing the first eight; more decompositions exist.
