Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598566, here are decompositions:

23 + 31598543 = 31598566
29 + 31598537 = 31598566
47 + 31598519 = 31598566
53 + 31598513 = 31598566
107 + 31598459 = 31598566
149 + 31598417 = 31598566
239 + 31598327 = 31598566
353 + 31598213 = 31598566

Showing the first eight; more decompositions exist.
