Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602020, here are decompositions:

3 + 31602017 = 31602020
97 + 31601923 = 31602020
139 + 31601881 = 31602020
157 + 31601863 = 31602020
211 + 31601809 = 31602020
277 + 31601743 = 31602020
313 + 31601707 = 31602020
349 + 31601671 = 31602020

Showing the first eight; more decompositions exist.
