Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597814, here are decompositions:

13 + 31597801 = 31597814
37 + 31597777 = 31597814
97 + 31597717 = 31597814
163 + 31597651 = 31597814
211 + 31597603 = 31597814
307 + 31597507 = 31597814
331 + 31597483 = 31597814
397 + 31597417 = 31597814

Showing the first eight; more decompositions exist.
