Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598942, here are decompositions:

3 + 31598939 = 31598942
19 + 31598923 = 31598942
31 + 31598911 = 31598942
79 + 31598863 = 31598942
103 + 31598839 = 31598942
163 + 31598779 = 31598942
241 + 31598701 = 31598942
421 + 31598521 = 31598942

Showing the first eight; more decompositions exist.
