Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598968, here are decompositions:

29 + 31598939 = 31598968
41 + 31598927 = 31598968
59 + 31598909 = 31598968
101 + 31598867 = 31598968
179 + 31598789 = 31598968
197 + 31598771 = 31598968
251 + 31598717 = 31598968
281 + 31598687 = 31598968

Showing the first eight; more decompositions exist.
