Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162030, here are decompositions:

13 + 162017 = 162030
19 + 162011 = 162030
23 + 162007 = 162030
31 + 161999 = 162030
47 + 161983 = 162030
53 + 161977 = 162030
59 + 161971 = 162030
61 + 161969 = 162030

Showing the first eight; more decompositions exist.
