Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597946, here are decompositions:

13 + 31597933 = 31597946
19 + 31597927 = 31597946
67 + 31597879 = 31597946
73 + 31597873 = 31597946
103 + 31597843 = 31597946
229 + 31597717 = 31597946
307 + 31597639 = 31597946
397 + 31597549 = 31597946

Showing the first eight; more decompositions exist.
