Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598458, here are decompositions:

41 + 31598417 = 31598458
131 + 31598327 = 31598458
137 + 31598321 = 31598458
179 + 31598279 = 31598458
191 + 31598267 = 31598458
197 + 31598261 = 31598458
257 + 31598201 = 31598458
317 + 31598141 = 31598458

Showing the first eight; more decompositions exist.
