Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597914, here are decompositions:

37 + 31597877 = 31597914
41 + 31597873 = 31597914
71 + 31597843 = 31597914
113 + 31597801 = 31597914
137 + 31597777 = 31597914
151 + 31597763 = 31597914
193 + 31597721 = 31597914
197 + 31597717 = 31597914

Showing the first eight; more decompositions exist.
