Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599832, here are decompositions:

23 + 31599809 = 31599832
59 + 31599773 = 31599832
71 + 31599761 = 31599832
149 + 31599683 = 31599832
179 + 31599653 = 31599832
233 + 31599599 = 31599832
269 + 31599563 = 31599832
281 + 31599551 = 31599832

Showing the first eight; more decompositions exist.
