Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598676, here are decompositions:

7 + 31598669 = 31598676
29 + 31598647 = 31598676
139 + 31598537 = 31598676
157 + 31598519 = 31598676
163 + 31598513 = 31598676
227 + 31598449 = 31598676
257 + 31598419 = 31598676
313 + 31598363 = 31598676

Showing the first eight; more decompositions exist.
