Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599774, here are decompositions:

7 + 31599767 = 31599774
13 + 31599761 = 31599774
47 + 31599727 = 31599774
67 + 31599707 = 31599774
71 + 31599703 = 31599774
103 + 31599671 = 31599774
163 + 31599611 = 31599774
211 + 31599563 = 31599774

Showing the first eight; more decompositions exist.
