Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599698, here are decompositions:

199 + 31599499 = 31599698
211 + 31599487 = 31599698
349 + 31599349 = 31599698
439 + 31599259 = 31599698
541 + 31599157 = 31599698
709 + 31598989 = 31599698
751 + 31598947 = 31599698
787 + 31598911 = 31599698

Showing the first eight; more decompositions exist.
