Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598666, here are decompositions:

19 + 31598647 = 31598666
313 + 31598353 = 31598666
367 + 31598299 = 31598666
439 + 31598227 = 31598666
487 + 31598179 = 31598666
523 + 31598143 = 31598666
733 + 31597933 = 31598666
739 + 31597927 = 31598666

Showing the first eight; more decompositions exist.
