Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598722, here are decompositions:

5 + 31598717 = 31598722
53 + 31598669 = 31598722
131 + 31598591 = 31598722
179 + 31598543 = 31598722
263 + 31598459 = 31598722
359 + 31598363 = 31598722
401 + 31598321 = 31598722
443 + 31598279 = 31598722

Showing the first eight; more decompositions exist.
