Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598622, here are decompositions:

31 + 31598591 = 31598622
79 + 31598543 = 31598622
101 + 31598521 = 31598622
103 + 31598519 = 31598622
109 + 31598513 = 31598622
163 + 31598459 = 31598622
173 + 31598449 = 31598622
199 + 31598423 = 31598622

Showing the first eight; more decompositions exist.
