Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598234, here are decompositions:

7 + 31598227 = 31598234
43 + 31598191 = 31598234
97 + 31598137 = 31598234
223 + 31598011 = 31598234
307 + 31597927 = 31598234
433 + 31597801 = 31598234
457 + 31597777 = 31598234
541 + 31597693 = 31598234

Showing the first eight; more decompositions exist.
