Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598376, here are decompositions:

13 + 31598363 = 31598376
23 + 31598353 = 31598376
97 + 31598279 = 31598376
109 + 31598267 = 31598376
137 + 31598239 = 31598376
149 + 31598227 = 31598376
163 + 31598213 = 31598376
197 + 31598179 = 31598376

Showing the first eight; more decompositions exist.
