Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620002, here are decompositions:

13 + 31619989 = 31620002
181 + 31619821 = 31620002
241 + 31619761 = 31620002
613 + 31619389 = 31620002
643 + 31619359 = 31620002
691 + 31619311 = 31620002
811 + 31619191 = 31620002
823 + 31619179 = 31620002

Showing the first eight; more decompositions exist.
