Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162072, here are decompositions:

13 + 162059 = 162072
19 + 162053 = 162072
61 + 162011 = 162072
73 + 161999 = 162072
89 + 161983 = 162072
101 + 161971 = 162072
103 + 161969 = 162072
149 + 161923 = 162072

Showing the first eight; more decompositions exist.
