Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598754, here are decompositions:

37 + 31598717 = 31598754
53 + 31598701 = 31598754
67 + 31598687 = 31598754
71 + 31598683 = 31598754
107 + 31598647 = 31598754
163 + 31598591 = 31598754
211 + 31598543 = 31598754
233 + 31598521 = 31598754

Showing the first eight; more decompositions exist.
