Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599598, here are decompositions:

47 + 31599551 = 31599598
167 + 31599431 = 31599598
257 + 31599341 = 31599598
659 + 31598939 = 31599598
809 + 31598789 = 31599598
827 + 31598771 = 31599598
881 + 31598717 = 31599598
911 + 31598687 = 31599598

Showing the first eight; more decompositions exist.
