Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598732, here are decompositions:

31 + 31598701 = 31598732
211 + 31598521 = 31598732
283 + 31598449 = 31598732
313 + 31598419 = 31598732
331 + 31598401 = 31598732
379 + 31598353 = 31598732
433 + 31598299 = 31598732
541 + 31598191 = 31598732

Showing the first eight; more decompositions exist.
