Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597862, here are decompositions:

19 + 31597843 = 31597862
61 + 31597801 = 31597862
211 + 31597651 = 31597862
223 + 31597639 = 31597862
313 + 31597549 = 31597862
379 + 31597483 = 31597862
409 + 31597453 = 31597862
601 + 31597261 = 31597862

Showing the first eight; more decompositions exist.
