Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598408, here are decompositions:

7 + 31598401 = 31598408
31 + 31598377 = 31598408
109 + 31598299 = 31598408
181 + 31598227 = 31598408
229 + 31598179 = 31598408
271 + 31598137 = 31598408
307 + 31598101 = 31598408
379 + 31598029 = 31598408

Showing the first eight; more decompositions exist.
