Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598562, here are decompositions:

19 + 31598543 = 31598562
41 + 31598521 = 31598562
43 + 31598519 = 31598562
103 + 31598459 = 31598562
113 + 31598449 = 31598562
139 + 31598423 = 31598562
181 + 31598381 = 31598562
199 + 31598363 = 31598562

Showing the first eight; more decompositions exist.
