Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597952, here are decompositions:

19 + 31597933 = 31597952
73 + 31597879 = 31597952
79 + 31597873 = 31597952
109 + 31597843 = 31597952
151 + 31597801 = 31597952
223 + 31597729 = 31597952
313 + 31597639 = 31597952
349 + 31597603 = 31597952

Showing the first eight; more decompositions exist.
