Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597562, here are decompositions:

13 + 31597549 = 31597562
79 + 31597483 = 31597562
109 + 31597453 = 31597562
151 + 31597411 = 31597562
331 + 31597231 = 31597562
349 + 31597213 = 31597562
433 + 31597129 = 31597562
463 + 31597099 = 31597562

Showing the first eight; more decompositions exist.
