Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599914, here are decompositions:

13 + 31599901 = 31599914
37 + 31599877 = 31599914
43 + 31599871 = 31599914
103 + 31599811 = 31599914
211 + 31599703 = 31599914
601 + 31599313 = 31599914
607 + 31599307 = 31599914
757 + 31599157 = 31599914

Showing the first eight; more decompositions exist.
