Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599650, here are decompositions:

97 + 31599553 = 31599650
151 + 31599499 = 31599650
163 + 31599487 = 31599650
211 + 31599439 = 31599650
337 + 31599313 = 31599650
457 + 31599193 = 31599650
547 + 31599103 = 31599650
661 + 31598989 = 31599650

Showing the first eight; more decompositions exist.
