Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599808, here are decompositions:

41 + 31599767 = 31599808
47 + 31599761 = 31599808
101 + 31599707 = 31599808
137 + 31599671 = 31599808
179 + 31599629 = 31599808
197 + 31599611 = 31599808
257 + 31599551 = 31599808
419 + 31599389 = 31599808

Showing the first eight; more decompositions exist.
