Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598372, here are decompositions:

19 + 31598353 = 31598372
73 + 31598299 = 31598372
181 + 31598191 = 31598372
193 + 31598179 = 31598372
229 + 31598143 = 31598372
271 + 31598101 = 31598372
439 + 31597933 = 31598372
499 + 31597873 = 31598372

Showing the first eight; more decompositions exist.
