Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598432, here are decompositions:

13 + 31598419 = 31598432
31 + 31598401 = 31598432
79 + 31598353 = 31598432
193 + 31598239 = 31598432
241 + 31598191 = 31598432
331 + 31598101 = 31598432
421 + 31598011 = 31598432
499 + 31597933 = 31598432

Showing the first eight; more decompositions exist.
