Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598680, here are decompositions:

11 + 31598669 = 31598680
89 + 31598591 = 31598680
137 + 31598543 = 31598680
167 + 31598513 = 31598680
257 + 31598423 = 31598680
263 + 31598417 = 31598680
317 + 31598363 = 31598680
353 + 31598327 = 31598680

Showing the first eight; more decompositions exist.
