Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598832, here are decompositions:

43 + 31598789 = 31598832
53 + 31598779 = 31598832
61 + 31598771 = 31598832
79 + 31598753 = 31598832
131 + 31598701 = 31598832
149 + 31598683 = 31598832
163 + 31598669 = 31598832
241 + 31598591 = 31598832

Showing the first eight; more decompositions exist.
