Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598634, here are decompositions:

43 + 31598591 = 31598634
97 + 31598537 = 31598634
113 + 31598521 = 31598634
211 + 31598423 = 31598634
233 + 31598401 = 31598634
257 + 31598377 = 31598634
271 + 31598363 = 31598634
281 + 31598353 = 31598634

Showing the first eight; more decompositions exist.
