Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598928, here are decompositions:

5 + 31598923 = 31598928
17 + 31598911 = 31598928
19 + 31598909 = 31598928
41 + 31598887 = 31598928
61 + 31598867 = 31598928
71 + 31598857 = 31598928
89 + 31598839 = 31598928
139 + 31598789 = 31598928

Showing the first eight; more decompositions exist.
