Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598232, here are decompositions:

5 + 31598227 = 31598232
19 + 31598213 = 31598232
31 + 31598201 = 31598232
41 + 31598191 = 31598232
53 + 31598179 = 31598232
89 + 31598143 = 31598232
131 + 31598101 = 31598232
199 + 31598033 = 31598232

Showing the first eight; more decompositions exist.
