Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599002, here are decompositions:

13 + 31598989 = 31599002
79 + 31598923 = 31599002
139 + 31598863 = 31599002
163 + 31598839 = 31599002
223 + 31598779 = 31599002
601 + 31598401 = 31599002
811 + 31598191 = 31599002
823 + 31598179 = 31599002

Showing the first eight; more decompositions exist.
