Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598888, here are decompositions:

31 + 31598857 = 31598888
109 + 31598779 = 31598888
241 + 31598647 = 31598888
367 + 31598521 = 31598888
439 + 31598449 = 31598888
487 + 31598401 = 31598888
661 + 31598227 = 31598888
709 + 31598179 = 31598888

Showing the first eight; more decompositions exist.
