Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598938, here are decompositions:

5 + 31598933 = 31598938
11 + 31598927 = 31598938
29 + 31598909 = 31598938
71 + 31598867 = 31598938
149 + 31598789 = 31598938
167 + 31598771 = 31598938
251 + 31598687 = 31598938
269 + 31598669 = 31598938

Showing the first eight; more decompositions exist.
