Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598534, here are decompositions:

13 + 31598521 = 31598534
157 + 31598377 = 31598534
181 + 31598353 = 31598534
307 + 31598227 = 31598534
397 + 31598137 = 31598534
433 + 31598101 = 31598534
523 + 31598011 = 31598534
547 + 31597987 = 31598534

Showing the first eight; more decompositions exist.
